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

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.

Incorporating push buttons into an Arduino project can allow you to take your projects to that next level. Switches are pretty simple, but you do need to understand how to use pull up and pull down resistors in order to get your circuit to operate reliably. This video explains the concepts in a simple manner.

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