If you want just the arduino, you can get an official arduino uno R3 here:

https://amzn.to/3TDu0mz

You can pick up the kit I am using in these lessons here:
https://amzn.to/3c9SJrO
The kit includes all the components I use in this class, and an arduino clone.

In this lesson we learn how a photoresistor works. We look at the solid state physics that allow the resistance to change with changing light levels. We then make a simple project where the arduino switches LEDs based on whether or not there are lights.

Also, you can get the Mastech Digital Voltmeter I am using here:
