Falstad’s simulator does not provide us with a form of photoresistor, so we will simulate it with a variable resistor (specifically, a resistor controlled by a slider). A zener diode provides a voltage reference, keeping the + input of the op-amp about 6V above ground. The threshold varies to make it less likely that the output will switch rapidly back and forth due to a noisy input near the threshold. Resistors. Current flows from a positive voltage source through one of two resistors to ground. Figure 5: Falstad circuit simulation for studying timing circuits. The MOSFET is in saturation, so the current across it is determined by the gate-source voltage, which is constant. The inverter is based on “logic” voltages. When you click the set input, it goes low, and this brings the Q output high, even after the set input goes high again. Use the Falstad circuit simulator to design a very simple circuit for your breadboard powered by your waveform generator that alternately flashes an red and a blue light emitting diode (LED) a couple of times a second.
