The world’s first cloud-controlled Etch-a-Sketch #Huzzah

Matt Welsh has built a robotic Etch-a-Sketch that can be controlled from anywhere via the internet.

For the last year, I’ve been working on a side project at home which I call Escher. It’s a robotic Etch-a-Sketch that can be controlled over the Internet from anywhere in the world. It’s made possible by the Adafruit Feather HUZZAH32 development board, and Google Firebase to provide the control between the Etch-a-Sketch and a web client.

Escher is controlled by an Adafruit HUZZAH32 development board, which features an ESP32 processor running at 240MHz, 520KB of SRAM, 4MB of flash, and integrated 802.11b/g/n and Bluetooth. This is a great little development board that is fully supported by the Arduino programming environment.

Escher uses two NEMA17 stepper motors to control the knobs of the Etch-a-Sketch. These are controlled using the Adafruit Motor FeatherWing board, making it easy to control each stepper motor either independently or together (as we’ll see in the software section below).

It also sports an easy web interface that lets you upload images to draw, or even draw with your finger directly on the virtual Etch-a-Sketch screen, which will then get drawn on the real Etch-a-Sketch.

All the files are on GitHub. You can check out the web interface at https://teamsidney.com/escher (requires an access code to use)

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.
