This EInk display with ESP32S2 WiFi is running CircuitPython to get the current bitcoin price and display it on the 2.9″ e-paper. There are 4 neopixels on the front and 4 buttons, and we got the neopixels + buzzer working today so it can alert you audibly. On the back, 4 SMT standoffs screw into magnetic feet often used for RGB matrix displays. That means we can attach it to anything ferrous like this AV stand! – video.
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.
