My requirement is to design a circuit that would provide a LED unit with control vide a dawn / dusk controller and a flasher. A switch helps the user select whether the LED is flashing based on the dawn / dusk controller output (LED flashes in night time only and off during day time) or, keep the LED flasher switched ON all the time, irrespective of day or night.
Here is my circuit for your comments, which will help me improve the circuit. The trim pot at the bottom (220/510) is to indicate the tuned value (approx 220 M Ohm for a flash rate of 1 Hz) and the maximum value (510 M ohm) of the trimpot.
