Chattering relay

[Ioannis]

Thanks picster. It works very reliable, especially in my case where the value does not change too quickly.

I see your software worked but you might need more capacitor filtering of the A/D voltage input, especially when operating relay

I always do Averaging or Darrels Analog Oversampling from 12 to 14 bits. 16 bits is better of course but takes too long.

The other option (just spitballing here) would be to put a cap across the coil. It slows down the coil release. Not very useful if you need the relay to release fast, but I have used it in a couple of oddball cases over the years.
