Using random numbers with Arduino

This tutorial covers using random numbers with Arduino, focusing on the random and random seed functions. It includes setting up a simple circuit with LEDs and resistors, using the Arduino IDE, and writing code to generate random numbers. The tutorial explains the concept of pseudo-randomness and how to achieve true randomness using the analog read function. Finally, it demonstrates how to use random numbers to control LEDs, providing a practical application of the concepts discussed.
