This is our new Bluetooth RC car - based on our favorite Arduino UNO! In this project as you can see we used a custom-made PCB board and the ATmega328P microcontroller. The board is specially design for this project and for small RC models. You can simple control it from your Android phone or tablet via Bluetooth. From the Android application you can also turn on/off the front and rear lights and play a horn sound! For our RC model we used only 3x1.5V AA batteries!

Android Application

To control your new Bluetooth car, download and install this Android application:

https://play.google.com/store/apps/details?id=braulio.calle.bluetoothRCcontroller

Credits for the Android app goes to Andi.Co! Thank you for sharing!

First enable Bluetooth and establish connection with BT module (pair it with your phone from bluetooth settings).

(ex. HC-06, password 1234)

Note: From the settings menu select the "On change/touch" option and then press the save button.

Functions that are working with this project:

  • 8 direction buttons
  • Speaker button for horn sound
  • Front lights button
  • Rear lights button

Well Done!

That's it!I hope you liked this, let me know in the comments!

EXPANDED TECHNICAL DETAILS

Remote Mobile Command

This RC car project eliminates traditional radio remotes, replacing them with any Android or iOS device.

  • Bluetooth Link: Uses the HC-05 or HC-06 Bluetooth module. The Arduino listens for single-byte character commands (e.g., 'F' for Forward, 'S' for Stop) sent from a smartphone app.
  • Power Stage: Managed by an L298N H-Bridge motor driver, capable of driving two DC motors with up to 2 amps of current.

Custom Software Features

  • App Connectivity: Pairs with various "Bluetooth Controller" apps on the Play Store, or a custom one built in MIT App Inventor.
  • Smart Safety: The firmware includes a "Signal Timeout" feature; if the Bluetooth connection is lost, the car automatically brings the motors to a safe stop.
