My AdaBoxDrawBot is a small robot that uses colored pens to draw on the surface it’s moving around on. It’s built from Adafruit’s AdaBox 002 and some additional parts. I used a custom FeatherWing with a MCP23008 I2C 8 bit port expander and a ULN2803A to drive a pair of 28BYJ-48 stepper motors.
It runs a version of my ClassBotLib (see https://github.com/russhughes/ClassBo... for more information) modified for the FeatherWing. I am currently working on porting the ClassBotLib from Arduino to micropython. I’ll be documenting the build and will post it on GitHub.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
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.
