I recently wrote a post about building a FreeTouchDeck an open source DIY alternative for Stream deck. In this post, I will show you how I added an air mouse feature to it. For this project, I used the following components Replace BLE-keyboard by BLE-Combo The FreeTouchDeck uses T-vK/ESP32-BLE-Keyboard library to set up the device […]
