Arduino, Elecrow or Raspberry Pi?
« on: Mon, 13 November 2017, 13:15:21 »
For a while I've been pondering a small low-powered computer to do simple things like monitoring indoor temperature, showing a few status LEDs for critical services, maybe even some sort of basic home security (although limited to, say, monitoring open doors/windows).

Massdrop have a steady stream of Arduino, Elecrow (NodeMCU) and Raspberry Pi-based learning kits with various capabilities and/or sensors included.

Although I've knocked up a few things in the (distant) past, I have never played with these relatively modern devices.

Network connectivity is a must, whether wired or WiFi (wired probably preferred, to lessen the likelihood of vulnerability attacks).  I'm not averse to a bit of soldering, but plug and play would be a bonus.

Any comments or suggestions?

Massdrop kits are like these:

The kits are fine.. But I don't recommend them to adults, because the kits are mostly designed for kids projects.

If you're an adult,  Think of what you'd like to build FIRST,  then buy whatever it is you'll need.. because it's probably not in the kit anyway..


For something cheap like raspberries,  don't bother with massdrop, because why wait a whole month so you can save $2..  just buy it msrp..

Arduino is great for robotic stuff, but it's not a great "computer" or anything needing real computing power or, more importantly, bandwidth. If you want it to move something or turn something on, Arduino is fine, especially in cases where once setup you will never mess with it ever again. That said, the way you have to compile and upload firmware for minor changes is a real pain in the neck and can make troubleshooting a very, very time consuming affair since you have to edit, compile, upload test, and repeat. While still great for certain things, in terms of capabilities, they are a bit dated.

I have no experience with Elecrow, but looking at it, it may be newer and/or more capable than the Arduino, but the Pi still has advantages.

Pi works well for things like what you want to do. It can be used as a computer, has lots of IO ports, tons of expandability and has FAR, FAR more computing power. While troubleshooting an Arduino is a hassle, the Pi is easy, you can connect a mouse, keyboard and monitor and directly edit anything in real time. One major benefit to the Pi, if you decide this whole thing is just a bad idea, the Pi can still be used for other things, like a cheap web browser or file server.

TL/DR
An easier way to look at all of this is that the Pi is a computer with a controller system, the others are simple controllers. If you lose interest in this project, the others will be worthless and sit in a junk drawer while the Pi can be repurposed in far more ways.

I agree with TP, most of this stuff is too cheap to bother with Massdrop.

I was kinda leaning towards the Pi from a general purpose computing sense anyway.

However they are (in Australia anyway) somewhat more expensive than the other solutions, and all of them are generally less easy to acquire down here.

The NodeMCU apparently has Lua baked into it, which I started to learn a while back and which has prompted the decision, although Lua could be run on the Pi too.

The kits include lots of sensors, such as temperature, proximity, light, which just plug into the main controller board.  This simplicity is a plus.  Haven't seen as many simple pluggable sensors for the Pi.

tp4's suggestion is good - a NodeMCU plus temperature sensor might be sufficiently cheap to put one in each of a few rooms, whereas a Pi could be used for more intensive things, like service status and data aggregation from the NodeMCUs.

Perhaps a combination of the two/three units would be the way to go.

Thanks for the comments so far - any further input is welcome :)

Ditto what Leslieann said.
I've got a couple boards, and my best advice is don't be lured by slightly more powerful, but less common boards. It's all about the ecosystem and support, stick with the big brands like RPi and Arduino.

Currently using one Raspberry Pi 3 model B and am definitely getting one more, probably two more though if I'm honest with myself. :D
They are amazing little machines that are useful for all kinds of (small) projects.

From my very limited experience with rpi temperature sensors, the DS18B20 is the fan favorite.

To answer your original question, yeah I think rasberry pi's will be best for your needs. Arduinos are usually purpose built controllers for robotics or simple circuits etc. In this case, the RPI will have a more general use case, and will allows you to do a winder range of tasks .. because .. let's be real, no one sets these up and leaves them. I'm always moving mine around to new tasks.

I have a Pi and Arduino clone (Elegoo MEGA 2560 R3).

From what I can tell, the Arduino is for stand-alone purposes (often called a 'Microcontroller') while the Pi is better suited for things on a network since it's effectively a little Linux desktop with all kinds of IO connectivity.

Sounds like the Pi is what you're looking for.

Yes, although for my initial use case (environment sensor/logging) either would suffice.

However the Pi does allow for considerably more reuse options.

I recently discovered the Onion Omega2.

https://onion.io/omega2/

Runs LEDE (Linux, a fork of OpenWRT - https://openwrt.org/docs/guide-quick-start/start), and has connectivity similar to RPi.

It's also considerably cheaper than a Pi - costs around $60 for a RPi but only $15 for an Omega2Plus (the "Plus" has more memory, more storage and a microSD slot).

For my purposes an Omega2 would be more than sufficient.

Anyone used these?

Alot of it comes down to support as well.

It might well be just as good, or even better,   but if you're going to be debugging something..  There's going to be loads more help available and other PEOPLE who know what's going on you can ask for a Pi,  rather than a lesser ubiquitous kit..


If you're uber tech-savvy,  this might not affect you..

Once again, yes, it may be cheaper, but with the way these are designed, by the time you outfit it the same as a Pi, you will have spent more. There is no vid port, no ethernet port, no usb port...

But you don't need everything on the Pi, for now.
If you later decide  to repurpose the Omega, you will be spending more, IF parts are to be found. What if the 3 is out by then and not interchangeable?

Here is another thing you may want to consider, you can connect a mouse, keyboard and monitor right to a pi and troubleshoot. Arduino, you make a change, compile code, upload, then cross your fingers that you fixed it. No? Make a change, recompile code and try again.

I've used Arduino on 3d printers then switched to Smoothie and Raspberry Pi, Smoothie uses a single, plain text config file, Pi you can diagnose it directly, you might not think it's a big deal, but I tell you what, it is a world of difference. I really, really hate trying to troubleshoot Arduino. You can spend as much time trying to get the firmware to flash as you spend diagnosing it, Smoothie and pi you pull the card and edit a file and or connect direct. The same goes for connections, their claim to fame is being cheap, problem is, it's not hard to see why it's cheap, they stripped it of everything. I'd much rather spend a little more and just get a Pi, rather than trying to solder a usb connection, HDMI port or ethernet port to that thing. It's just not worth the hassle

I know quite a few people with Arduinos, LOTS of them, and most get used once then shoved in a box. It's a single use controller. This will be the same because once you solder some connections you sure aren't going to want to deal with it again.


Also, $60 for a Pi?

Some excellent points - thank you for spending the time to provide such a comprehensive response.

Once again, yes, it may be cheaper, but with the way these are designed, by the time you outfit it the same as a Pi, you will have spent more. There is no vid port, no ethernet port, no usb port...

I don't need all the functionality of a Pi, really.  Don't need a video port (haven't got an HDMI-enabled monitor anyway), and the Omega has WiFi built-in.  You can get an expansion dock (couple of USB ports, power/reset switches, header) for AUD$17, and even an ethernet expansion dock for AUD$17.

But you don't need everything on the Pi, for now.
If you later decide  to repurpose the Omega, you will be spending more, IF parts are to be found. What if the 3 is out by then and not interchangeable?

My initial use cases are simple - first off simply monitoring temperature in my computer room.  The second would be to control a bunch of LEDs.  Not much beyond that.  if I ever needed to extend one of them, and a version 3 was available, at that price I'd probably just get a 3 plus whatever I needed to make it useful.

Here is another thing you may want to consider, you can connect a mouse, keyboard and monitor right to a pi and troubleshoot. Arduino, you make a change, compile code, upload, then cross your fingers that you fixed it. No? Make a change, recompile code and try again.

I've used Arduino on 3d printers then switched to Smoothie and Raspberry Pi, Smoothie uses a single, plain text config file, Pi you can diagnose it directly, you might not think it's a big deal, but I tell you what, it is a world of difference. I really, really hate trying to troubleshoot Arduino. You can spend as much time trying to get the firmware to flash as you spend diagnosing it, Smoothie and pi you pull the card and edit a file and or connect direct. The same goes for connections, their claim to fame is being cheap, problem is, it's not hard to see why it's cheap, they stripped it of everything. I'd much rather spend a little more and just get a Pi, rather than trying to solder a usb connection, HDMI port or ethernet port to that thing. It's just not worth the hassle

As above, I'm unlikely to use the full functionality of a Pi.  I have gone through the cluster of computers phase, and come out the other side with one small server running Linux, which does almost everything I need.  I have a second server on standby for the rare occasions when I need an MSSQL server, but even that database runs on Linux now.

So my use cases don't require super-powerful processors, heaps of RAM, or lots of connectivity - simple WiFi and ssh will suffice.

As for troubleshooting, I've probably spent more time troubleshooting things via command line than most people have in a GUI, and it's usually a lot easier.  My use cases wouldn't require much troubleshooting, anyway.  And anything that arises beyond that would be an interesting learning experience.

I know quite a few people with Arduinos, LOTS of them, and most get used once then shoved in a box. It's a single use controller. This will be the same because once you solder some connections you sure aren't going to want to deal with it again.

Solder?  Nah - just use the expansion dock, like a Pi.  I already have a bunch of breadboard wires, and also a couple of breadboards.  All I'd need is the expansion dock.

Also, $60 for a Pi?
I know you pay more in Australia, but they retail for $35 here and you can sometimes find the Zero for $5, which has usb and hdmi built in.

Yes, it sucks trying to buy technology down here sometimes.  If you can't get one for $2 from China, then you end up paying top dollar.

https://www.littlebirdelectronics.com.au/raspberry-pi-3~38194

AUD$52.36, and that's just for a bare Pi 3 Model B.  On top of that is a power adapter (about AUD$20) and memory card (AUD$24.94 which includes NOOBS).

Even a Pi Zero W is AUD$20:

https://www.littlebirdelectronics.com.au/raspberry-pi-zero-w

So this Omega2+ for $15 is tempting.  Even including the expansion dock it only comes to AUD$32.

Why would you buy a prebuilt install of Noobs, it takes like 5 minutes to install on any card.
Same for power, who doesn't have an old cell phone charger, and if not, China does for $2.

Also have you not considered a Pi Zero?
Seems to have more connections than even the Omega, and it's cheaper and smaller in size.

I'd have to buy an SD card - I've never had any reason to collect them.

I have a box full of power bricks.  I tried to find a working one recently, one was dead, one was alarmingly hot, one was buzzing, and one worked (of those that actually had the right plug on them).  Most are at least 5 years old.  Not sure I'd trust a chinese one ...

As above, a Pi Zero W would cost me $20, or $21 with header soldered on (Omega2+ is $15).  Pi PSU is $18 (looks like it needs a microUSB plug - I do not have any PSU with that).

Shopping list would be:

Omega2+ $15
expansion dock $17
total: $32

Raspberry Pi Zero W with headers $21
PSU $18
4GB SD card $13 (from the same vendor for simplicity)
total: $52

Still cheaper, although I do appreciate the Pi's ecosystem and support.

Would you use a computer without an SSD ?

A slow SD card relative to a "fast" one is ON PAR with that kind of difference.

Cheapie sd cards are mind numbing-ly slow

You have been warned. !!

None of my computers have SSD.

So there.

The Raspberry Pi is not so blindingly fast that a really fast and expensive SD card is going to make much difference, if any.

However, I am with TP about the SSD... I just can't.

I've been waiting for computers most of my life.

From a unit test quite that takes nearly 10 minutes to run, a compile that takes 2 or 3 minutes, a software update check that takes up to 5 minutes, reports that take 30 seconds, file transfers that take up to an hour, I wait.

My ideal is a computer that responds to any query or request within 2 seconds.

From a unit test quite that takes nearly 10 minutes to run, a compile that takes 2 or 3 minutes, a software update check that takes up to 5 minutes, reports that take 30 seconds, file transfers that take up to an hour, I wait.

My ideal is a computer that responds to any query or request within 2 seconds.

Hahahahahaha, right?

+1000.

There's little excuse for delays in modern computing. Things that used to be fast are slower today, even.

Most of my waiting occurs from UI delays. iOS is the absolute worst for it with its input-blocking during/after every single animation (ie. after every single input).

Slow web pages and software due to "fancy" looking UI that runs slowly and just gets in the way is the norm these days and for some reason, everyone just accepts it.

It's amazing to me how programmers used to come up with very clever ways of programming to make a program work with very specific amounts of memory, but now RAM is not even a consideration, among other things. The bloat that's in programs, webpages etc. today is ridiculous, I agree.

FWIW, I have a Raspberry Pi B version 1 (I bought it right before the updated model because the designers used to say it would never be revised), and I've never used it for anything.  :)) I used it as a video game emulator a little bit, but then I realized I have a full sized desktop computer right in front of me that would perform better.

I've reached the stage with servers where I'll set one up, then wonder what I'm actually going to do with it.

So I have reduced my server farm to 2 servers, one of which is not on most of the time.

The Pi (or whatever) has a very specific function, so something small and low-powered is preferred.

A great article summarising some of the Raspberry Pi altenatives available now:

I still haven't got one, but decided to get a Pi when the dust settles and I have more time and money to actually do something with it.

Subscribing for future updates  :thumb:

Might have to grab a few for pdf/dotfile backups, light compiling, music, and other light duty/low power/low heat computing tasks.

I read about the ATtiny85 in a local electronics magazine.  It is basically an Arduino in an 8 pin DIP.

Unfortunately it didn't have enough i/o pins for me, so I looked at the ATtiny84, which is the same but in a 14 pin DIP.

I ended up getting 4 of those and an Arduino Uno R3 for this project.  A RPi would have been more flexible, and is still on my wish list, but for this project I'm probably going to end up with a few of these things with some LEDs attached around the place, and the lower the cost the better.

The ATtiny worked out at about $4 each, I already have (too many?) LEDs and resistors, most of what I need at absolutely minimal cost.

Maybe one day I'll actually get a RPi and drive the whole lot from there instead of trying to get them to drive each other.
