Once you know how to control motors and LEDs using Arduino, the final step is to put everything that you have learned so far and make it a standalone product. There are multiple ways you can achieve this:
The simplest method is to use your hands.
Using two different Arduinos or using external motors
Using existing real-life devices
Even though you learned about controlling motors and LEDs, if you are doing this for the first time, you will take some time to understand the synchronization of LEDs and motors. The easiest way to test Persistence of Vision is to use your hands for rotation. Before you start rotating the complete setup, make sure you have uploaded the latest sketch to Arduino, connected some standalone battery/power source, and firmly fixed your LEDs on some base. As a base, you can use a thermocol sheet or cardboard, and fix them using some electrical tape.
Once you have fixed all the materials, you can rotate your PoV, and...
