Brief look at discovered problems with using LM358 op amp as a single supply comparator

Table of Contents

I looked at using the LM358 op amp as a comparator circuit a lot closer than usual and discovered some stuff that I show in the video below. This is just my quick discoveries shortly after making the video covering the circuit build. It helped me better understand what I have read in the past of problems with using op amps as comparators. In the future I am sure I will be able to make a better video covering these topics.

Turns out that I probably only got away with this circuit because I was using 5 volts Vcc, and was lighting LEDs with the output.
