On the meter I have (a EDMI ES-10B), one blink represents 1/1000th of a [[wp>Kilowatt-hourkWh]]. |

| It's a really simple circuit, basically connect the light dependent resitor (LDR) to the 5V pin on the Ardunio, then connect back to GND with a 100k resistor between the LDR and GND. Connect the analog data pin (A0) just after the LDR. | It's a really simple circuit, basically connect the light dependent resitor (LDR) to the 5V pin on the Ardunio, then connect back to GND with a 100k resistor between the LDR and GND.
