All we need to do is duplicate the code for pin 8, and change the pin numbers to pin You should be able to see both LEDs blinking. It reads each line and performs the task before moving onto the next line.

How to use WS2812B RGB LEDs with Arduino

I am quite new at arduino. I have a arduino uno board.

Getting Started with the Arduino – Controlling the LED (Part 1)

Consent to store personal information: I agree to let Circuit Basics store my personal information so they can email me the file I requested, and agree to the Privacy Policy. Email me new tutorials and very occasional promotional stuff: The analogWrite function that you will be using in the main loop of your code requires two arguments: One telling the function which pin to write to, and one indicating what PWM value to write.

In order to fade your LED off and on, gradually increase your PWM value from 0 all the way off to all the way on , and then back to 0 once again to complete the cycle. In the sketch below, the PWM value is set using a variable called brightness.

Controlling the Arduino’s LED

Each time through the loop, it increases by the value of the variable fadeAmount. If brightness is at either extreme of its value either 0 or , then fadeAmount is changed to its negative. In other words, if fadeAmount is 5, then it is set to If it's -5, then it's set to 5. The next time through the loop, this change causes brightness to change direction as well.
