How can I transform this circuit so that the output voltage not depending on the supply volt...
Instead of feeding the amplifier output back to R2 and Runlabelled, put a resistor in series with the amplifier output, and a pair of back to back silicon diodes to ground, and connect R2 and Runlabel …

Schmitt Trigger hysteresis
You design the comparator to be suitable for your input signal.
Input signal swings within the hysteresis band will be ignored, signal swings outside the hysteresis band will be followed.
If your in …

How is a latch different from Schmitt Trigger?
They differ in the level of the signal that is required to change their state.
In a Schmidt trigger, a relatively small, well-controlled change of signal level is needed. The input is designed to acc …

Schmitt Trigger Comparator 0 - 5V
Have you tried using an amplifier that goes to 5v?
In the bad old days, most amplifiers would only go to within a volt or two of the positive rail, LM324 for instance.
These days, you can get ampli …

How repeatable is the output from an opamp
The main specifications you are looking for are 'long term stability' and 'temperature coefficient of offset voltage'.
Where you are looking to make a very precise comparison against a reference, it …

I need help debouncing a push button
Any hardware solution to debouncing involves a certain time latency, what time T between button presses is considered to be a bounce, or a second press?
Once you have that time T, the simplest way to …
