How do I adjust the delay time on this module?
The delay time is set using the onboard potentiometer. Turning it clockwise increases the delay; counterclockwise decreases it. The typical range is 0–10 seconds, depending on the RC components on the board. You can also change the capacitor or resistor to alter the range.
