Select the DC Voltage position on the multimeter.
Power is ON when measuring voltage.
1. Measure the voltage drop across the LED. (1.7V red, 2.3V green, 3V – 3.2V other)
2. Measure the voltage drop across the 220R resistor. (3.3V red, 2.7V green, 1.8V – 2V other)
3. Measure the voltage drop across the 10uF capacitor when the button is pressed and released. (start at 5V, fade to 0.1V)
4. Measure the voltage drop from the emitter (NPN transistor) to GND when the button is pressed and released. (start at 4.3V, fade to 0.1V)
