Manual

Encoder modules will soon be available for the rover which allow you to count how many steps each motor has
rotated. Knowing how each step translates to linear displacement, you can ensure the robot moves in straight
lines and the movements are repeatable.
Q. The motors are noisy, how can I make them quieter?
Use the grease included with the Tamiya dual gearbox and add capacitors to the motors.

You can also cover the top and bottom of the gear box with tape.
Q. The drive wheels fall off the motor shaft, what can I do?
Rough up the shaft with some sandpaper and add a dab of glue inside the sprocket bore (hole) before pressing
it onto the shaft.
Q. Are there any other configurations for the tracks or motor?
We have not tested any other configurations (shorter track length, use different hubs/ sprockets in different
locations etc.) though you are free to try. Ensure the tracks are not overly tight so the motors can turn freely.
Q. One of the LEDs arrived broken what can I do?
If it arrived broken, RobotShop will exchange the PCB at our cost. Please contact us for an RMA.
Q. Is the DFRobotShop Rover edible?
This was not included in our testing
Programming
Q. Where can I find additional sample code for the board?
The board is directly compatible with Arduino Software available for download via www.Arduino.cc Take note
that four of the pins are used for the H-bridge (pins 5, 6, 7, 8). Additional tutorials and sample code are
available via www.arduino.cc
Q. Can I use other software to program the board?
Yes, though you may need to change the bootloader; this is done via the ICSP headers. The most common
alternative software is C / C#.
Q. Can I do a quick motor test?
Copy/paste the following code into Arduino to run the motors continuously at full speed:
/* Copy and paste the code below into the Arduino software */
void setup(void)
{
int i;
