    Anyone using Arduino?

    We are about to invest in some Aduino Clones for our primary school after many months of me playing around with various projects.

    I have not found anything as easy to use and as fun as these little £10 boards. Well apart from this > Olimex DUINOMITE-MEGA maximite basic computer

    Is anyone else using them? Experiences?

    I use them for ...err <ahem>, personal projects. They are very good and the library support is excellent for a wide range of devices.

    I still have a fondness for PicAxe kit. It's cheaper with simpler support circuitry requirements, so when all you need is a little bit of programmed logic, it's a sensible choice.

    I've got some Digisparks for personal use they could be interesting for students?

    These are similar to the digispark, a cutdown nano and less that £4 :-)

    What do you use your digispark for?

    £10 Arduino clones? What are they? Ardunios are £30!

    Thanks for that link. That's a nice cheap solution for embedding in a final project - and I have a use for one!

    You can buy Uno's for £13. ATmega 328's with caps and resonator can be had for <£4 - you need to provide an external serial interface - usually something like USB to TTL to do the programming - and some breadboard or other means of laying out a circuit.

    If you want a school friendly supplier try here They do a 10% discount if you order a good whack of them. I have been using this brand for a few months and they work flawlessly.

    On ebay, the nano can be had for £7 pro mini for £4 and a Arduino Mega for £11 all delivered to your door from China. I have one of each and they all work and have had no problems.

    Nice,

    I built a binary counter shield with a 595 shift register. And played with this which was fun (and easy to build) Cheap too.

    Those sub-£4 nanos need an external usb interface. For the money, a complete arduino for £12ish is a steal, all you need is a usb A-B cable - they can also be powered from usb (like a Pi) so you can use a spare phone charger charger. If you're really on a shoestring, cannibalise old kit for leds, motors, transistors, ir tx / rx bits.

    Arduinos can also program attiny micros - I have a few attiny45 smd's for sale if anybody wants them (hard to get in small numbers).

    I just completed an incubator monitor. It displays the temp and humidity and sounds an alarm if either goes too far out of wack.

    It should be noted that there is a project which can connect Scratch to an Arduino which I got working last year.

    First person to get it into a primary curriculum wins!

    In a sense the exact opposite end of the process for my Arduino PID which was controlling a slow cooker to do Sous Vide.
