Bluetooth remote control
By Le Dinh
This is the second revision of a Bluetooth remote control treaded chassis using a Nokia E75 smartphone with xyz accelerometers for control. Pulse-width modulation is incorporated to enable independent speed variation of each motor.
Major components include the $45 RN-41-SM Bluetooth module (available at Mouser.com), Atmel ATtiny2313 AVR Microcontroller, L298N H-bridge, and a voltage booster (available at Pololu.com). Treaded chassis is a Tamiya kit which is cheap and not great quality. Total cost is around $110.
Code for the microcontroller / smartphone and schematic are available at sourceforge.net/projects/roboticscode/files in the folder named 'Bluetooth Remote Control Tank'. This is the PWM revision which is a bit more complicated than the non-PWM version so you may feel more comfortable digesting the non-PWM code first.
