A program that detects whether there's some amount of light and starts playing a song with a buzzer. This program will run on Arduino. It detects the amount of light using a LDR sensor. Most of its ...

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 ...

Working of LDR controlled LED using Arduino. As per the circuit diagram, we have made a voltage divider circuit using LDR and 100k resistor. The voltage divider output is feed to the analog pin of the ...

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 ...

This paper focus on the idea of automatic lightning system and peculiar way of implementation with embedded tool systems. The proposed method is used to measure and control the intensity of light in ...
