Love your work mate! What is the purpose of the resistors on the inverting input and are they necessary? The circuit examples I've have seen just have it straight to ground? Cheers.
Glad to hear! Most op amp circuits are dual power supply, which means ground is (usually) half way between a positive and a negative voltages. This is a single supply op amp circuit, which means the supply voltages are +5V and ground of 0V. So to get a half way voltage (2.5V) I just used 2 equal value resistors as a voltage divider.
it helped me grasp that op-amp hysteresis thing, thanks
Glad to hear, thanks for watching!
Interesting demonstration!
Thanks!
