Ive decided to use this design. I ordered the 741. The rest of the components I have.
The LM311 version had issues (according to the comments) from the site where it originated from.
This one is very well documented and included an explanation of and implementation for hysteresis. Something Ive been wanting to understand.
I added LED D2 so i can observe the circuit working and R2 in addition with the pot so the value does not go to 0.
Feedback about this design is welcome.
Thank you.
