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.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
