The circuit applies a 5V pulse, the main clock, to diode D1and capacitor C1 to form a peak-hold circuit. Cthen discharges at a rate that P1 sets.

High-brightness LEDs, with independent delay and duration, find use in a visual-inspection application. The circuit is not complex, but it saved the day in an application involving visual inspection of the spray pattern of fuel injectors for quality and consistency.
