You can build an IoT telegraph with analog feedback servos, QT Py ESP32 S2 and Circuit Python. 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 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 handles position and sends it over WiFi using Adafruit IO as the broker.
