Step 1: Materials
- Twelve 10Kohm resistors
- Eight NPN transistors
- Lots of small jumper wires
- A Breadboard to assemble it on
10Kohm resistors are not essential. What I mean by that is that you may substitute them for different resistors. Any combination of resistors with a value between 4.7 Kohms and 100 Kohms will work in this project.
