Step 1: Gather the materials
The resistors are as follows
9 270 ohms(5% resistance)
3 10k ohms(5% resistance)
You will also need a power source. I hooked up my Arduino to my computer.
You will need a chord to connect the Arduino to the computer
Make sure everything works and then continue
Step 2: Make a diagram
Step 3: Start building
I will show each new step in red wiring, and the old ones in blue.
