I’ve been interested in learning more about programming microcontrollers and saw that Adafruit has a low cost board (called trinket) that is very convenient since it can be programmed over USB. When I first got my hands on this, I was making sketches for it using the Arduino IDE, but wanted to dive in at a lower level and be able to write C code and reprogram the Attiny85 chip that is on board. There are many different ways to do this, but here is the way I went about doing it.
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, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
