New board! http://arduino.cc/en/Main/ArduinoBoardDue  Lookit all that friggin' I/O. Cortex M3 at 84 MHz, native USB, 54 GPIO pins, 12 analog ins and 2 12-bit DAC outs! Music makers, this is your fuckin' jam. Looks like it's going to go for $50ish. Arduino 1.5 will support compiling to it, and has some other nice usability bumps.

Base Emitter posted:Just what I want, and just what I want it for. As best as I can tell, it's straight C, with some libraries. When you compile, the Arduino IDE slaps some boilerplate up top and adds a main() at the end before it compiles and sends it over. Pompous Rhombus posted:Repostin' this cuz I was hoping for an answer. There's a lib for that! Check out the following link, it should get you started. http://arduinostuff.blogspot.com/2011/05/receiving-and-sending-ir-with-arduino.html

Our vaporizer project is moving along nicely. My filthy trick for expanding the gnd and +5 rails for various pots and LEDs and doodads: An IDE connector off an old cable. Hard to photograph this one, sorry.  The last two pins on the far end are not connected to the bus, so that they can pass through pins 8 and 9, which we are using just for structural integrity.  Built connectors out of 2 row headers, pins on one side, wires strain-relieved through the other side. Also laced the harnesses  Yay! It works! And now poo poo doesn't short out when I wiggle it!

ArchNemesis posted:Likwise, be careful before attaching any old shield to it. The pinout is backwards-compatible, but if you have a shield feeding 5V into one of the inputs, you're gonna fry your chip. It's strictly 3.3V. That said, there are some very interesting and promising libraries already out for the Due, most exciting of which (for me) is the Scheduler. --- Just got linked to this today. Hey, wouldn't it be cool to send and receive small data packets wirelessly from your gadget? ....THROUGH SPACE? http://rockblock.rock7mobile.com/ Rockblock uses Iridium sats to send and receive data. Obviously per-byte it's very expensive, but the pricing really is reasonable for what you're getting. Think of the possibilities for roaming/autonomous vehicles.

Acid Reflux posted:Finally just headed over to Radio Shack and bought an Uno yesterday. Already in love with the whole concept, and I don't even remotely understand the programming language yet. What I *do* understand is that I was controlling the position of an RC servo via a small pot in a little under 20 minutes...it's the little things that make me happy. Congratulations on writing some C!  Seriously, Arduino's language is C with a little bit of sugar in the IDE to insert the right headers and such, and some predefined functions to set things up for you.

You could do something like this for your Vcc and Ground lines. e: (idk if imgur is broken or what, http://i.imgur.com/3ITx52u.png is the pic) That's an IDE connector with the back snapped off and the cable pulled out. One bare copper wire is soldered almost all the way down the length of each side (I left the far pin on each row unconnected), and two male pins are soldered sticking down, to go into +5 and Gnd. The last pair of pins is isolated and has a pin soldered to each, so that it will plug into pins 8 and 9 (for structural strength) but will pass them through to the top of the header so that they're not wasted. I got +5 pins for dayyyyyys.
