An M5Stack touch screen can provide a quick and easy user interface. Here, we use it with an Arduino Uno to control the sequencing of an RGB LED.

Gamepad (prototype) based on M5StickC (ESP32 Pico) with I2C joystick module, dual button unit, and Bluetooth Low Energy connectivity.

This project uses a retail water level setup with a few modifications to add the capability of wireless level sensing.
