Your robot army, controlled by Arduino and Bluetooth Open-source hardware project shrinks Arduino, adds wireless, creates awesome.

The watch is built around an Arduino Pro Mini, a scavenged Nokia LCD, and a BlueSMiRF Gold. The Bluetooth connects to a Nokia N900 with a little Bluetooth client app [Ahmet] wrote.

This Bluetooth module ties directly into the Tx and Rx lines of the Arduino so a wireless serial connection between an Android device can be established.

The tutorial runs a bit fast, and you’ll probably want to check out Nedelkovski’s previous tutorials if you’re not sure how to connect your phone to the Arduino board over Bluetooth.

The $22 kit includes an Arduino-BLE board and 6-pin header that should be fairly broadly applicable for building Arduino-based hardware that can communicate with iOS devices.

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 ...
