**Warning**
|
|
|
|
This activity involves opening an electronic toy, cutting its wires and reconnecting them. Your toy could end up becoming totally useless. Hacking has its risks and rewards!

## Materials
|
|
|
|
* toy RC car with 4 or 6 AA batteries
|
|
* 1 @boardname@ (optionally, another @boardname@ too if you want radio control)
|
|
* wire trimmer
|
|
* small Philips screw driver
|
|
* [1 Kitronik motor driver](https://www.kitronik.co.uk/5620-motor-driver-board-for-the-bbc-microbit-v2.html)
|
|
|
|
## What's our hack plan?
|
|
|
|
Most toy RC cars use 3 small DC motors to operate:
|
|
* 1 DC motor to spin (torque) the back wheels
|
|
* 1 DC motor to spin (torque) the front wheels
|
|
* 1 DC motor to steer the front wheels
|
|
|
|
What we're going to do is open up the RC car, remove the existing electronic controller, and replace it with the **Kitronik** motor driver that controls 2 DC motors. We will connect the two torque motors to one controller and the steering motor to the other controller.
|
|
|
|
After the motor driver is connected, we will use a @boardname@ to control it. Also, we can use another @boardname@ as a radio controller for the @boardname@ that's in the car.

**Getting a car to hack**
|
|
|
|
Ask friends or family members if they have any old RC cars lying around. Scout around at thrift shops and other second hand stores for donated RC cars.
