This mini tutorial will cover how we use barcode scanners. This isn’t necessarily an Arduino project, but it is a tool that we use every day when shipping packages – instead of entering in invoice numbers, we use a barcode scanner. That way we don’t have to worry about humans making typos!
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.
