Project #5: Logic Probe #2
1. Touch the probe to a 5V source. What happens?
The display outputs a 1.
2. Touch the probe to source ground. What happens?The display outputs a 0.
3. Can you decide what would happen if a digital pulse were applied to the probe? Explain how this would work.The display would show a 1 when the signal is high and a 0 when it is low because when a voltage from the probe is high, it interrupts the flow of electrons flowing through the transistor, causing it to shut off the 4 LEDs powering the "0". At the same time, when the voltage on he probe is high, it lights up the LED for the "1".
Any questions?
