Controling fan rotation using PWM and spindle gauge
Easy scenario. Students should move the flap in the lab
Target group
This hands-on lab guide is intended for the Beginners.
Prerequisites
Generally students need skill using servo. For realising scenario, students need access to documentation for servo and understanding PWM control method.
Scenario
- using schematic, check servo connection,
- using ESP documentation check registers with PWM controling,
- write the program which:
- send value 0 as duty of PWM,
- wait 15 seconds,
- send value 50 as duty of PWM,
- wait 15 seconds,
- send value 100 as duty of PWM.
- using the camera observe display flap position.
- You can use other wait time and value of duty, but wait time should allow observe effect by camera (against net lag)
Result
On display should be visible flap closed, middle position, full open.
Start
Check the start flap position.
Steps
Instead using built-in PWM, you can send “0” and “1” for obtain required duty factor.
Result validation
Only way for validation is check flap position by camera.
