Based on a Nordic Semiconductor 32-bit ARM system-on-chip that has built-in support for Bluetooth 4.0, the RFduino runs the same code as Arduino UNO ... has developed a "shield" for the CR2032 ...

For instance, you can adjust the cutting height, add sensors for obstacle detection, or even integrate it with a home automation system. The DIY Arduino robot ... and Adafruit provide a wealth ...

Controlled by an Arduino Uno, the robot uses a Slamtec RPLIDAR sensor to help map out its surroundings. The microcontroller is also armed with a Bluetooth link and an SD card for storage.
