§Arduino Serial Plotter:

§Running arduino-serial-plotter webapp

Arduino Serial Plotter uses WebSockets to communicate by sending or receiving commands.


  • Node v10
git clone
# or when using ssh:
# git clone
cd arduino-serial-plotter-webapp
npm i && npm start

Default port: 3000


The Arduino Serial Plotter will send a request to our CLI and the CLI is waiting for a connection on the websocket, this is why you need to open the arduino plotter app after starting the CLI:

http://localhost:3000 (with default port 3000)
