The ultimate gadget for your presentations: A ESP32 and the magic of the BleKeyboard library (https://github.com/T-vK/ESP32-BLE-Keyboard )
Navigate through your slides effortlessly as you wield the ESP32, sending "Enter" key commands via Bluetooth to your PC.
But wait, there's more! We've added the perfect gimik, - a laser pointer nestled within the presenter. With just a short click, the "Enter" key dances across the screen, moving you one slide closer to presentation perfection. And when you need to accentuate a point or highlight critical details, a long click activates the laser pointer, allowing you to cast a spotlight on brilliance.
- We use a selfmade Class for controlling the Button clicks
- The BleKeyboard library takes care of the bluetooth connection and pairing
- A short click <500ms will send a KeyStroke to the PC
- A long click >500ms will start the laserpoint
