Hi all
i brought a cheap energy monitor from ebay (~10?) and i would like to connect to Arduino to read the values.
The device uses an ADE7755 chip (Energy Metering IC with Pulse Output)
Im a noob in electronics but the idea was to connect the PWM signal to arduino and read (using maybe interrupts?). I disconnect the LCD, and connected GNG to Arduino GND and PWM pin to a PWM pin in arduino.
. And then the device died (some resistors burned) :S
The LCD board receives the pulses in white wire, and does the math over time. (the yellow wire is not used).
X pulses correspond to 1W.(datasheet)
It should be easy to connect this device to Arduino?
Any suggestion would be great
Thanks
