My second Arduino project. A basic remote controlled car with twin engines, one for each wheel. Getting to grips with how Arduino works, and since I know second to nothing about electronics, I'm learning about that too.

More info after the break.

Hardware used:

- Arduino Mega
- Arduino Duemilanove
- Tamiya 70097 Twin-Motor Gearbox
- 2x Tamiya 70098 Universal Plate Set
- Tamiya 70144 Ball Caster Kit
- TB6612FNG Dual Motor Driver Carrier
- RF Links 4800bps Receiver+Transmitter - 315MHz
- 250 mAh 9V NiMH battery to power Arduino
- 1100mAh 3.7V LiPo battery to power motors

On the software side I used:

- VirtualWire
- WiiChuck.h

At the moment there is quite a bit of delay between the controller and the car actually responding. Will try to iron that out and then think of something fun to do with this basic robot chassis.

The first version looked like this, but I found that the tank tracks created too much friction and made the robot go a bit too slow.
