I made this one in the sim using schmitt triger. I found many sources but with odd resistor values. But the sim is showing different results.
The first problem is when using 3V supply everything is getting flat after A2, so output is 0V. This was obvious because the max voltage of the schmitt triger was 1V so I changed the supply to 1V and the problem was happening between A2 and A3, the functionality of this part is to keep the voltage above the threshold voltage of the trigger or something I may not know. It is not doing that, so the output is again 0.
Blue is after A2 and green is before A3.
As shown here in https://www.youtube.com/watch?v=AWlRGLxm7nc that should be like this
What is the problem in my circuit? I mean using resistors between 1M and 1R
