Hey All,
I am tinkering with a dark sensor circuit. I have it working as noted in the schematic which I borrowed from a YouTube video. A couple questions so to better understand and add to what seems like a simple project.
I understand the function of R2 is to prolong life of LED. Correct?
What is the function of R1?
I have seen many schematics similar to this with the major difference being R1 and R2 values. Are these resistor values dependent on the source and load?
My goal is to add this circuit to this LED string.
Besides the Source changing from 3V to 4.5 volts and the single LED load changing to an LED string. What else if anything needs to change to have the circuit integrated into the LED string?
Thanks,
TRU
