The idea is very simple: we press a button and send a request to our website which then increases The Sandwich/Coffee Count. The design isn’t much harder than that – thanks to RaspberryPi we can build a very basic circuit (power -> button -> line out to RPi -> LED -> resistor -> ground, it doesn’t get much simpler than that) and then just “catch” the signal and voila! RPi sees the signal and fires out a POST request.
Each Friday is PiDay here at Adafruit, be sure to check out our posts, tutorials and new Raspberry Pi related products. Have you tried the new “Adafruit Raspberry Pi Educational Linux Distro”? It’s our tweaked distribution for teaching electronics using the Raspberry Pi. But wait, there’s more! Try our new Raspberry Pi WebIDE! The easiest way to learn programming on a Raspberry Pi.
We now have Raspberry Pi Model B with 512MB RAM in stock and shipping now!
