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.’
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
