Reading from a CT Sensor pin affected by Seven Segment Displays switching on and off

Hi 6v6gt,
Thanks for the input regarding pullup resistor on the analog pin. I was able to find information on its use on a digital pin but nothing for an analog pin, so was just experimenting a bit.

Re: voltage output from the TA12-100.
The output is always positive as you can see on the serial plotter screenshot. I have taken a sample from the serial monitor below to make it a bit clearer.

I don’t understand this either, as there appears to be nothing on the TA12-100 apart from coil, resistor and connectors. The photo attached is identical to the unit I’m using.

Re:Code
If this is what you mean by sychronisation, then I am doing this. Have you had a look at the code I’m using to monitor the CT Sensors Post#10? It would be good to get your feedback on this.
