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.

In Connecting to Intel® Edison from Android* with Bluetooth* LE (BLE) describes a way to access BT via Arduino code but additional BT shield/kit is required.

This Arduino code basically based on serial communication concept. When the microcontroller receives a serial data, then it will perform a specific task pre-programmed by the user. For example when ...

A perl script running on the iPhone will then send the command to the Arduino. When it receives the start command, the Arduino will ground the wire to the remote start and fire up the car.

Thanks to the LightBlue Bean+, however, one of those roadblocks has been torn down. The Bean+ is basically an Arduino board that can be programmed via Bluetooth LE.

Arduino has introduced a Nano shaped board with a Wi-Fi and Bluetooth LE capable Espressif’s ESP32-S3 microcontroller, supporting it with the Arduino IDE and MicroPython. “Beginners can explore in an ...

Living proof is this human-following robot/car that was build by the YouTuber over at DIY Builder, which relies on an Arduino Uno as the brain of the device. The video that you can find embedded ...

The Arduino code tells us that the valves will be opened as long as the remote up/down channel is above/under given values.

Randy Sarafan, who also happens to be the Technology Editor over on Instructables, gutted a remote-controlled car and swapped the parts for an Arduino board.
