Jan Axelson’s books and website are the best resources for anyone doing USB development. Well written, concise and complete – if you’re doing any kind of USB dev you’ve either run across her work or (like us) own half her books!
Jan Axelson is the author of seven books about computers and electronic technology, including USB Complete, Serial Port Complete, USB Mass Storage, and Embedded Ethernet and Internet Complete. Jan’s articles have appeared in Embedded Systems Programming, EDN, Circuit Cellar, Nuts & Volts, and other publications. Bill Machrone of PC Magazine has described Jan’s writing as ‘a model of clarity and conciseness.’
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.
