From Step 3: Why does this circuit use a diode at D3 instead of a pull-up resistor? Select the best answer. Diodes are directional components that only allow current to flow one way. Without a diode at D3, current could flow backward through the circuit, preventing it from working correctly. When SW1 is not pressed, a jumper wire or resistor would still allow the junction at the low side of SW1 to be pulled high, causing the red LED at D1 to light up. We have not used basic diodes yet this quarter. This allows them to be included in the lab activities. When SW1 is pressed, a resistor would pull the junction with D1 low, causing the red LED at D1 not to light at the moment it is supposed to.
