I have the MK125 working as intended but what I’d now like to do is to get it to respond to the red flashing light on my electricity meter, which can flash maybe twice a second. I have the LDR on a long wire and it seems to pick up the signal but there is too much of a delay.
My intention is to get a pulse from the relay in the light rather than the dark phase, which looks quite feasible.
What is the best way to reduce the delay and also do I have the best photo cell for the job?
