A proof-of-concept vending machine shows how we can dispense with cash for everyday purchases, skipping credit and debit cards altogether and going straight to electronic transfer. The vending machine uses QR codes, PayPal, a smartphone camera and Twitter. And, to complete the geek-buzzword bingo checklist, the hardware is based in part on Arduino, an open source hardware platform.
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.
