 You can build an IoT Telegraph with analog feedback servos and CircuitPython. Inspired by ship engine telegraphs, this uses analog feedback servos to make a simple, yet modern, two-way communication system. Use it to keep in touch with a friend by letting them know when you want to grab a bite to eat, go on a walk, or just get together for a cup of coffee. These emojis represent the activities you're interested in and the 3D printed handle lets you select the one you'd like to do. A piece of copper tape is used to detect when it's being held and released thanks to the magic of capacitive touch. The analog feedback servo keeps track of the handle's position and sends it over Wi-Fi using Adafruit I.O. as the broker. Powered by the Adafruit Qtipi ESP32S2, this small, yet powerful dev board is packed with features perfect for IoT projects. It features the ESP32S2 Wi-Fi chip with 13 GPIO pins, capacitive touch, and native USB for running CircuitPython or Arduino. The CircuitPython code runs on two different dev boards and uses Adafruit I.O. for sending data between the two. The analog feedback servos are calibrated and record the position of the servo when it detects the handle has been touched. When touch input is released, the position of the servo is sent to a feed. Each Telegraph has one feed for publishing and a second feed for listening. To build your own, be sure to check out the guide on learn.adafruit.com. We hope this inspires you to check out CircuitPython and Adafruit I.O. for your next IoT project.
