Hi Guys,
I am currently practicing my reverse engineering skills starting at creating a schematic from an existing circuit board.
I have been able to draw the schematic based on a simple led circuit. (This is simplified and first part removed to meet forum restricted topic rules)
I am struggling to figure out what the electrolytic cap is doing (smoothing?) and why R1 is there.
I know what a zener diode does and how they work, but not sure what it is needed for here?
If someone could help me understand this I would be ever so grateful. I'm sure something will click with sudden realisation as soon as someone explains.
Thank You in advance
