# 01 - Install of  Visual Studio Code

To transfer the code to the microcontroller (ESP32 or TTGO) it is necessary to install[ Visual Studio Code](https://code.visualstudio.com/).

Once installed, you must install the [PlatformIO](https://platformio.org/install/ide?install=vscode) package which will be used later for all your projects and not only for the Dimmer or the Pv router.
