STEP 3 Now add a red LED (D1 in the main schematic) in series with 500N of resistance (shown as R1 in the main schematic). How you choose to arrive at 5002 is up to you. SW1 PSB D2 D3 1N4007 5 V D1 Blue Red R3 10 ka R1 500 Q • What happens now when SW1 is (and the PSB is turned on)? • What happens if you turn the diode at D3 around? (Don't forget to turn it back the right way afterward.) • Why does this circuit use a diode at D3 instead of a pull-up resistor? (Meaning, what would happen if a resistor were used instead of the diode?) pressed ( Previous Next 14 Dashboard Calendar To Do Notifications Inbox
