Schmitt triggers are voltage comparators that have 2 threshold voltages that cause the output to change state plus a middle ground voltage (hysteresis) where the output stays in the last state that it was put into.
This prevents rapid switching if the voltage is bouncing back and forth a tiny bit across any specific voltage.

Assortment of commonly used integrated circuits (IC). I made a lot of videos with them.
Diagram is explained in the video below.
Screwdriver set that I use in my videos.
These t connectors are really nice for quickly and easily connecting the end of one wire along part of a different wire.
- When pin 2 has less than 1/3 supply voltage to it, the output goes high.
- When pin 6 gets more than 2/3 supply voltage, the output goes low.
- From 1/3 to 2/3 supply voltage, the output stays in whatever state it was last put into. That’s the hysteresis range if using a 555 timer as a schmitt trigger.
