Hi.. I note there is a fairly current thread (I am trying to make a simple IR detector ) involving a cheap ir object avoidance detector.
I am working on one at the moment which is meant to count the passes of a 1 metre clock pendulum. The output goes low on detection. It is connected to another cheap Chinese module sold as a kit to time 30 or 60 seconds.
which I have modified it to count input pulses up to 24 and then reset to zero. The problem I'm getting is that upon detecting an object the count advances at superspeed by a random amount as though it was being fed with a relay with contact bounce. So I wondering if the OP amp comparator built in to the detector could be oscillating during the transitions. has anyone had any experience like this with this particular detector ?
