CODE

arduino

To control the motor with the Arduino Mega board (you can also use other cards like the nano version) you need to load the following code using the IDE software. Once the Arduino is connected to the PC and to the isolation board, use the IDE software serial monitors to control the motor using the commands: 1) a = switch the motor on at the speed already preset by the rxx command 2) s = turn off the motor 3) rxx: set the speed value (from 0 to 100) (for example r51 commands an adjustment to 51% of the maximum speed
