I have breadboarded the LM393 and I can't get it to work at all.
I have a multi-turn pot supplying each of the non-inverting inputs and I've tried setting these from 2.3 volts to 4.6 volts. Then I supply a voltage of more than the non-inverting input 'reference'. The output never changes.
Rather than belaboring this issue does anyone have drawing of the LM393 that works? Please feel free to email me if possible to help me solve my misunderstanding of how this should work.
