Connect the A0 pin of the Arduino to the same column where the LDR and resistor is connected (Since the LDR gives out an analog voltage, it is connected to the analog input pin on the Arduino. The ...

Connect the A0 pin of the Arduino to the same column where the LDR and resistor is connected (Since the LDR gives out an analog voltage, it is connected to the analog input pin on the Arduino. The ...

Light and dark detection using an LDR. For this project, let’s stick to the LDR sensor module so we can select the light or dark detection by placing jumpers. We’ll be using this module to detect ...

Controlling Relay using LDR with Arduino Instead of controlling an LED according to the brightness and darkness, we can control our home lights or any electrical equipment. All we have to do is ...

Learn here to interface RGB LED with Arduino. Circuit Diagram: The complete circuit diagram of this project is given above. The +5V and ground connection shown in the circuit diagram can be obtained ...
