In this experiment we are going to work with a sensor which is a resistor that depends on light. In a dark environment, the resistor will have a very high resistance. As photons (light) land on the detector, the resistance will decrease. The more light is we will have a lower resistance. By reading different values from the sensor, we can detect if is it light , dark or a value between them. Another element that we are going to use on this experiment is Piezo Buzzer.
So what is it ?
It’s an electronic device commonly used to produce and signaling a procces that is happening through a sound, beep or etc. The Piezo buzzer produces sound through electricity. Some uses of Piezo Buzzer: e.g clock alarm, alarms, car/truck reversing indicator, bells, timers etc. So we see that this element is used on a wide area of electronic devices.
