Drive your Arbot from a phone. Seriously.
The HC-05 is the go-to Bluetooth serial module for Arduino. Wire four pins, upload our Series 7 Bluetooth code (free on our downloads page), and students can steer their Arbot from any Android phone with a free controller app.
Features
- Bluetooth 2.0 serial (SPP) — appears as a wireless serial port
- Master/slave modes, AT-command configurable
- 3.3–6V supply, works with UNO R3 out of the box
- ~10m range — an entire classroom
The engagement cheat code: nothing gets a Year 8 class louder than robot races driven from their phones. Also ideal for wireless sensor logging and two-Arduino communication projects in Stage 5.
