Introduction: Arduino Using MPLAB X
I will be making a simple code to blink a LED using Arduino.
Step 1: Dealing With LED Using Arduino
We will begin by declaring the output pin
pinMode(ledPin, OUTPUT)
Make sure that all the code below is in the void loop
digitalWrite(ledPin, HIGH);
This statement is used to turn ON the LED
digitalWrite(ledPin, LOW);
This statement is used to turn off the LED
Finally we can put delay(n), where n can be any number depending on the time that we want to run to stop the LED.
Step 2: Sample Code
digitalWrite(ledPin, HIGH);
delay(5000);
digitalWrite(ledPin, LOW);
delay(5000);
