// Import dependencies
const SerialPort = require("serialport");
const Readline = require("@serialport/parser-readline");
// Defining the serial port
const port = new SerialPort("COM3", {
baudRate: 9600,
});
// The Serial port parser
const parser = new Readline();
port.pipe(parser);
// Read the data from the serial port
parser.on("data", (line) => console.log(line));
// Write the data to the serial port
port.write("ROBOT POWER ON");
port.write("ROBOT POWER ON");
