Introduction: Back and Forth Car
This car can be created from any old RC car that has a motor. This car is designed to go forward or backwards when it bumps into an object. It can also be turned into a game with two people which can be quite fun!
Materials Needed:
1X Old RC Car (or any car with a motor that drives the wheels)
4-6X Short Wires
1X DPDT Switch
3-5X Popsicle Sticks
Hot Glue
Needle Nose Pliers
Strip down your old car to just the motor leads and the battery case leads and the on/off switch. Attached two wires onto each of the motor leads and wire them to the switch as shown in the Fritzing diagram. Attach the negative and positive leads from the battery case to the switch as well.
Test out the connections and make sure that everything is working before you start hot gluing. The wheels should spin forward or backwards when you turn the on/off switch to on. Then when you switch the DPDT switch it should go the opposite direction. If this is the case then begin to hot glue the switch into a good place on the chassis. If it does not work, make sure that everything is wired correctly and also that none of the wires are touching. Be careful of short circuiting. If the batteries get hot at any point take them out and check your wiring.
There are many different ways to attach the switch and the lever onto the switch. Play around with it and find a way that works for you!
Test it out against a wall and see if it works or get a friend and play around!
