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.

How does the random function's behavior change when using a seed versus not using one?

What is the effect of using an unconnected analog pin with the analog read function for random seed?

What modifications are needed to the random function to ensure it returns numbers between 2 and 4?

What are the intricacies of using the random function and random seed that one should be aware of?
