This project uses the FrekvensPanel project to control the IKEA Frekvens Panel with additional the matrixled.ino to spin up a server to connect to your panel.
First, run the development server:
npm run dev
# or
yarn dev
# or
pnpm dev
Open http://localhost:3000 with your browser to see the result.
Open FrekvensPanel.cpp, FrekvensPanel.h from FrekvensPanel Project and matrixled.ino (in hardware folder) in Arduino IDE. Now flash the file to a NodeMCU / esp8266 device with WLAN module.
