How To Make It

1

Start with your circuit: power + wire + light sensor + wire + DC motor

2

Make 3 wheels. Trace a cup on cardboard to get perfect circles. What other objects can be a wheel? (Try a CD!)

3

Make the base out of cardboard. Cut a slot in the cardboard wide enough to fit the wheel.

4

Place modules on cardboard base. Use tape to hold the modules down.

5

Add wheel to the motor mate. You can use a pen to poke a hole through the wheel where the motor mate will go. Then place the motor mate onto the DC motor.

6

Poke skewer through two remaining wheels and glue them in place. These will be the back two wheels. The skewer will be your axle.

7

Now attach the back wheels. Cut a rectangle out of paper and fold it in half. Them place it over the axle and tape it down. (Tip: don't make it too tight. The axle should be able to spin.)

8

Time to drive! Optional: Draw and cut out a figure of your self to attach to the three wheeler. Now you have someone to drive it!
