I/O LED (Part 2)

Part 1, 2, 3, 4, 5, 6 In the previous example, we observed the discharge time of the parasitc LED capacitance. In this way, LEDs can be used as light sensors. Let’s now see what we could do else when combining the emitting properties of the LED along with its sensing properties. In the next application, an LED will light up […]
