Hi guys,

new to this so looking for advice. I have a PIC16F88 that has been configured to receive analog inputs on pin 12 using ADCIN command and then strobe a LED as an output on pin 8 using HIGH/LOW commands. I noticed that when the LED strobes, it induces the strobe signal on the analog input. I have played around with the circuit to ensure good ground planes exist etc but still same problem. Has anyone experienced this before and how can I eliminate it?

thanks

mark.
