## Power supply

The device needs (best) an external battery to power it or a 5V supply. A possible improvement would be to add a lipo battery (requires a voltage booster and a charge regulator).

## Usage

Just click on the esp32 "boot" button to pause (the LED should go out), then click again to restart.

## How to compile the project

Libraries required :
- SmartRC-CC1101-Driver-Lib by LSatan
- ezButton by ArduinoGetStarted

Then you can simply choose the code that suits you and compile it in an arduino IDE. (You'll probably need a board manager like esp32 by Espressif Systems to detect your esp)
