... Additional activity (if time allows or for further study) (Note: Use clear LEDs.) An LED can also work in reverse. That is, it can be used as a light sensor. Measure the voltage across one of your LEDs. Bring a white light source near the LED and note the increase in voltage. This should work for al ...
