Hi, Adafruit! I thought you’d want to hear about a robot built with your motor shield that made it’s first public appearance last night.
This is a wall-hanging, mural drawing robot. The code is [here]. And a set of assembly instructions is available [here].
It can draw pictures with commands sent from the the Arduino serial interface or it can be driven like an etch-a-sketch.
It understands g-code commands G0-G4,G90, and G91. (see: http://en.wikipedia.org/wiki/G-code)
Try uncommenting #VERBOSE in the Arduino code and see how busy that window gets
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.
