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.
