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 ...

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.

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 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 ...

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 ...

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 ...

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, ...
