Step 22: Create Arduino to Transistor Leads

Picture of Create Arduino to Transistor Leads
Cut two pieces of 22 gauge wire about 14 inches long and strip them on both ends.

Solder a 100 ohm resistor to the end of each wire.

These resistors help keep the amount of current that flows between the transistors and Arduino to a safe level.
