How an Arduino Program Works You need to know the meaning of the following things What is Arduino? Why Arduino? How do I use Arduino? The Arduino community calls a program a sketch. It has two main functions: setup and loop. void setup(){ } runs once, when the Arduino is powered on. void loop(){ } … Read more
What is Arduino? Arduino is an open-source electronics platform based on easy-to-use hardware and software. Arduino boards are able to read inputs – light on a sensor, a finger on a button, or a Twitter message – and turn it into an output – activating a motor, turning on an LED, publishing something online. You … Read more
