Switch press added – reduced pressure
This circuit IC1 is IC op amp circuit connected to an Integrator circuit. Operation of the circuit. When the press switch S1 will have positive current flow from the power supply Through resistor R1 to charge the capacitor C2. As a result the output of IC1, lower voltage to 0 volts. When the switch press switch S2, the voltage output level of IC1 is back. Increase nearly as quickly or until the supply voltage. When the buffer circuit IC1.Therefore, voltage output of IC1 is how much value will be passed to IC2 and the output voltage (Vout) that you want.
