“The Lawn Mower” is a RC Bluetooth car that I made for one of my CET classes. The car runs using a 9 volt battery for supply, two 5 volt regulators that feed the ATTiny85, Servo, Bluetooth Module, LN298N H-bridge IC, as well as the back dual DC motors.

The brains come from the ATTiny85 micro controller from ATMEL, it has 8 pins 5 which are usable. This allows me to use two for the LN298N to go back and forth, one for the servo, and two for the TX and RX on the Bluetooth Module.

ATtiny85Here you can see how the ATTiny85 is configured.

If you want to see it in action you can watch it here.
