I'm measuring LED pulses from a electricity meter using an LDR connected to the Arduino. I've attached the circuit, but in essence 5V - LDR - Split to Arduino_PIN2 and 150K to ground. The itself is connected to about 15m of very thin twin-core flex cable. The LED I'm trying to measure is quite dim…
