im using an optocoupler connected to the impulse led of the energy meter. i want to use the output of the optocoupler as interrupt in the atmega328. so that in every blink of the led, the counter will add one and that will be used to determine how many kilowatts was used. 1600 impulse/kilowatt. thanks for the help!
