Week 1: Actuators

Open to everyone

17 / 22

Getting started
Powering on the VirtualBench
Wiring a DC motor
Push-button switch board
Controlling a DC motor with PWM
Using the oscilloscope
PWM for signals
Conclusion

FGEN: 1x

Keep the FGEN probe at 1x, not 10x.

MAX 3V

DON'T USE MORE THAN 3V, THIS WILL BURN THE MOTOR

MEASURE: CH1

Use channel 1 to measure voltage, not FGEN.

Power the motor from the PSU through a motor driver, never directly from FGEN or an MCU pin.

Step 3: Using PWM to control a DC motor

Now wire it up like so:
