  • Will this board work in conjuction with the Atto Pilot current sensor? I want to be able to measure current and voltage without getting unwanted noise from the power supply. The Atto Pilot worked brilliantly with a 24V/3A DC power supply but when I went to a higher voltage and current power supply the sensor was unable to give correct readings and would crash the program every time I went to turn on the power supply or raise the voltage. I'm guessing that this was due to the noise created when the power supply turned on as I was able to connect the leads after the power supply was turned on and get readings. In doing this I ended up frying a chip on the Atto Pilot sensor and am unable to read current anymore.

    I'm thinking this optoisolator would need to go between the Atto Pilot sensor and the Arduino in order to filter out the noise that causes my program to crash. Is this true?

No public wish lists :(
