Arduino Explained: Random Brightness Using 1 LED

Random numbers are very useful if you need your LEDs or any project to behave differently each time it is run, instead of a definite set of behavior.

For this Arduino project, we will set the brightness of an LED with a random value every 100 milliseconds. To achieve this effect, you will need two Arduino functions: random () and randomSeed()

Hello, what app did you used to place virtually the jumper wires, led, and resister?

Thank you so much. So I presume it could be possible to randomize the delay value at the end with another int variable, something like random_delay_val?
Should it work with the same seed?
