Introduction: Control Your Tyco RC Car With Your Smartphone!

Hello everyone!

After one or two years that I follow all your projects, I decided to start to publish my own. To begin with I want to show a simple modification that I made some time ago on a RC car, making it controllable from a smartphone (Android).

The application I created with MIT App Inventor 2 and both it and the sketch are really simple to do!

P.s. Sorry for my english .. I know that is not the best! (I'm Italian☺ )

Step 1: Parts Required

  • 1x Tyco RC Car
  • 1x Arduino Uno (or another Arduino board)
  • 1x Bluetooth Module (I use: HC-05)
  • 1x 4 channel relay module
  • Application CarBot RC Bluetooth Arduino
  • Two batteries, one for power and one for engines
  • Smartphone android
  • Jumper Cables

Step 2: Mechanical Part

First of all undressing the body of Tyco!

Remove the outer houses and eliminate all the PCB inside, leaving tances the skeleton with the two motors and the wheels (the four cables that go to the motors, unsolder or cut just above the weld).

Here is a step-by-step guide.

Step 3: Mounting the Electronics

Now follow the schematics and all the modules connected to your Arduino!

For convenience, put the module into the battery box and secure it with glue or double-sided tape.

Step 4: App and Code


The program is really simple!

(I leave the download below)


It's time to check out our car!

  1. Visit Play Store
  2. Search application "CarBot RC Bluetooth Arduino" and download it!
  3. Once installed, open it and connect the smartphone to the car bluetooth
  4. Have fun!

Step 5: ​Update 2.0 

I later improved the machine, replacing Arduino Uno with Arduino Pro Mini, so it takes up less space and is all the more ordered (the schematic is the same!)

To do this, I created a basic floor made of wood, which I pasted on the machine. Once you have made your plan, we can position the components as we like!

Using hot glue go fix bluetooth, arduino, the battery and the PCB to adjust the voltage to 5 volts (the schematic is present in the photos)

Now you just need to connect the two batteries, one for the power of the electronic part (Arduino, bluetooth and ralay) and one for the motor supply, and connect your machine with your phone (using the application Carbot RC Bluetooth Arduino)
