Programming Joystick Motors at Half Speed

How do you program joystick motors at half speed or less, if possible?

Looks like you already had some help here.

The general answer is that motors use a control value that ranges from -127 (full reverse) to +127 (full forwards). To run a motor at less than full speed send a smaller control value.

Full speed.

motor port1 ] = 127;

approximately half speed.

motor port1 ] = 64;
