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
Step 2: Disassemble the Car
For this step, you will take the car apart. First, clip off the antenna using a strong pair of cutters. Then, remove the four screws that hold the body on the chassis and separate the body from the chassis. Next, remove the two screws that hold the internal electronics cover. Discard this cover.
Step 3: Remove the Antenna
Remove the screw holding the antenna. Cut the antenna wire near the printed circuit board being careful to only cut the black antenna wire. Discard the antenna and antenna wire.
