Arduino Beginner Project with LDR
A beginner arduino project which uses an LDR to turn ON a bulb when there is not enough light in a room. Visit this link for more detailed information about the project: https://maker.pro/arduino/tutorial/ho...
In order to detect the intensity of light or darkness, we use a sensor called an LDR (light dependent resistor). The LDR is a special type of resistor that allows higher voltages to pass through it (low resistance) whenever there is a high intensity of light, and passes a low voltage (high resistance) whenever it is dark. We can take advantage of this LDR property and use it in our DIY Arduino LDR sensor project.
