The feature sizes should be 4um by 4um, with a step height of 25nm. Explore different scan parameters based off of the values in Section 3.4, to see if you can obtain a better contrast image. If the scan appears unclear or irregular, see Section 3.6 for troubleshooting help. The obtained AFM image should be similar to Figure 14 below.

The motor control changes four output port pins on the microcontroller to control the motors. When the time comes to dispense a pill, the motor software goes through a state machine to switch each signal and turn the motor. When the sensor located on the carousel signals that one segment has passed, the motor stops rotating. Software Documentation
