Microcontrollers use pins to interact with the rest of the circuit. These pins will usually be one of input / output pins, vin or ground. I/O pins can be simple digital I/O pins, or they can have some special carachteristics like being able to vary the voltage of their output using pulse width modul...
In this very first example, a basic serial write operation is started from an Arduino device. void setup() { // put your setup code here, to run once: Serial.begin(9600); } void loop() { // put your main code here, to run repeatedly: Serial.println("Hello World!"); dela...
Node js code Sample to start this topic is Node.js server communicating with Arduino via serialport. npm install express --save npm install serialport --save Sample app.js: const express = require('express'); const app = express(); var SerialPort = require("serialport"); var po...
