The in band gain for these op amp circuits is calculated in the normal way ignoring the effect of the capacitor. Then when your Arduino output drives both the "threshold" and "trigger" inputs, the output will switch HIGH when the IN signal is above the reference, and switch LOW when the IN signal is below .5 of the reference. lot-to-lot variability of the output current caused by variability of the photosensitivity of the chip and the transistor gain. The output is clean, fast, and switched without bounce (an inherent problem with mechanical switches). Where: Xc is the capacitive reactance in ohms Π is equal to 3.142 f is the frequency in Hertz C is the capacitance of the capacitor in Farads. If you use 2 silicon diodes as shown then the switching points are about 1.4V and about 0.7V with a nice "schmitt trigger" action. Schmitt trigger based on the 4093 integrated circuit (1/4) The switching points are denoted by V 1 (low threshold) and V 2 (high threshold).
