Adafruit recently shared a prototype of their new TRRS AT Trinkey, a USB plug-in board equipped with a SAM D21 and a TRRS jack for developing customizable HID devices.

Secret Maze 2 This simple project, based on an ATtiny85, gives you a maze that you have to solve by navigating it with four push buttons. The available paths in each direction are shown by four LEDs: a lit LED means that your way is blocked by a wall, and the speaker beeps if you try to move in that direction. When you get to the goal all four LEDs flash, and a tune confirms you've succeeded! You can select one of six different mazes to solve.

Electronic Paper Electronic Paper (e-paper) is a technology developed to mimic the appearance of ink on paper. It reflects ambient light off of an electronically controllable pigmented surface. This is different from conventional display technologies such as LCD and LED which project images through direct light emissions. Electrophoretic displays are a type of e-paper that uses miniature capsules filled with charged particles of different colors capable of switching positions whenever an electric charge is applied. E-paper is visible under direct sunlight, uses less power, and provides a wider viewing angle than LED and LCD displays. Its low refresh rate and monochrome output are perfect for ebook readers, digital price tags, and this Digital Drawing Pad project.   Rotary Encoder A rotary encoder is a mechanical position sensor that converts rotational motion into an electrical signal using two disks, one stationary and one connected to a rotatable shaft, with partially overlapping conductive terminals that produce data lines that are 90 degrees out of phase with each other.   Accelerometer Additionally, an accelerometer is a microelectromechanical sensor that measures the rate of change in velocity from motion using a small mass connected to a fixed frame through a set of flexible springs integrated into a semiconductor chip.

Shake It Off! A Digital Drawing Pad Inspired by the Iconic Etch A Sketch.. In this project, which uses the Arduino IDE, we create and demonstrate a digital drawing pad using an ESP32-based e-paper display dev board, rotary encoders for drawing control, and an accelerometer for shake detection to initiate an erase.
