Step 1: Gather Materials and Tools
I used the following materials:
-RC Car - el cheapo from Walmart. It cost $6 at my local Walmart.
-Arduino - I used the Duemilanove purchased from Sparkfun, (www.sparkfun.com)
-4 1000 Ohm 1/8 Watt resistors (color code BRN/BLK/RED). The value of the resistors is not critical. Anything within 50% should work.
- 1/16th inch heatshrink tubing to insulate the resistors after they're installed
- 22 AWG solid wire. You'll need five wires, 6 to 8 inches long. I used Black for the Ground and White for the 4 control wires.
- a small amount of solder
- 2 rubber bands
- 9V battery clip that plugs into the Arduino, also available from Sparkfun
Tools you'll need are:
- small (not tiny) Phillips screwdriver
- wire stripper
- soldering iron
- "third hand" to hold resistors while soldering wires to them
- small tip diagonal wire cutters
- desoldering tool or braid
- tweezers or small needle-nose pliers
