This is a basic example how arduino works. In this arduino projects you’ll see how arduino control LED on for 1 second and off for 1 second repeatedly.
Instruction;
1) Connect cathode lead of LED (shorter lead) to ground pin and anode lead of LED (longer lead) to pin 13.
Upload this code to your arduino
/* Blink Turns on an LED on for one second, then off for one second, repeatedly.This example code is in the public domain. Code hosted at: arduinoprojects101.com */ void setup() { // initialize the digital pin as an output. // Pin 13 has an LED connected on most Arduino boards: pinMode(13, OUTPUT); } void loop() { digitalWrite(13, HIGH); // set the LED on delay(1000); // wait for a second digitalWrite(13, LOW); // set the LED off delay(1000); // wait for a second }
There is 2 section of code arduino running, first setup() function which run once and second loop() function running continuously.
In setup function pinMode 13 declare as OUTPUT.
