In final form, a Bluetooth module and Arduino Pro Micro are stuffed inside the stereo along with a DPDT relay to switch the I2C bus. An external button is used to trigger the Arduino to switch to ...

Creating a Bluetooth-controlled device with an Arduino Uno and an HC-05 Bluetooth module enables control of lights or even relays to manage AC appliances wirelessly using an Android smartphone.

After making the connection between the central bluetooth module and Arduino, I wrote some codes that are included in "central_BluetoothModlue.ino" Then the other Bluetooth module is connected to ...

Arduino - Controls the car's movements based on received Bluetooth commands. L298N Motor Driver - Powers and controls the car's motors. Ultrasonic Sensor HC-SR04 - Measures distance to obstacles and ...

In this project, we will make such a remote-controlled toy: a Bluetooth controlled car to be exact. The project is fairly simple to make, and all the components are cheap and easy to find. The brain ...

A FT-232 USB to serial board is used to program the Arduino. A standard Bluetooth module has to have HID firmware installed. [Dastardly] makes a homemade daughterboard–er, ...

The circuit is built around Arduino Uno (MOD1), ultrasonic sensor HC-SR04 (S1), HC-05 Bluetooth module (MOD2), buzzer (B1), and LEDs. The ultrasonic sensor is used to maintain proper distancing, and a ...
