This project shows the steps to change an ordinary remote control car to a Bluetooth (BLE) control car with Wombatics SAM01 robotics board, Blynk App and MIT App Inventor.

The are many lot cost RC cars with lots of features like the LED headlights and underglow lights. However, the remote controller came with the car cannot control lights and motors individually.  With mobile App and Arduino board, we can convert these ordinary RC Cars to a more advanced bluetooth control toys.

We are using an Arduino Compatible board with BLE (Bluetooth Low Energy), so that it works with both iOS and Android phone.

    Picking a RC Car

    We picked a Fast Lane 1:24 RC Car. This car is prefect for this project, as it has all features that we are looking for, such as headlight and underglow LEDs with enough room to put our board inside.

    Taking the Car apart

    After taking it apart, identify the wires for LEDs and motors.  The desoldering them off the board and replace them with Arduino board and motor drive module.

    Putting on the motor drive module

    In this step, solder the steering motor to "MOTO A" and back motor to "MOTO B" on the motor driver module. Solder jumper wires to headlight & under-glow LEDs on both +ve & -ve side.

There has been a great deal of value to me in my involvement with the project. Would like to share it with the car parking multiplayer mod apk unlocked everything team so they can also read it and implement something new.
