This is an Arduino library for interfacing with an LDR (Light Dependent Resistor) sensor. With this library, you can easily read the analog value of an LDR sensor connected to your Arduino board. To ...

2x Arduino Uno boards (one for the sensor node and one for the central system) Xbee or NRF24L01 wireless modules (2x for communication between nodes and central system) DHT22 (or similar) temperature ...

Components Required for Building the Light Following Robot Arduino UNO R3 x1 LDR Sensor Module x2 2WD- Two Wheel Drive Robot Car kit (includes the acrylic frame, Wheels, BO Motors, Castor Wheel, ...

Our Smart Home Using Arduino Uno R4 WiFi project is designed for home safety and convenience, integrating temperature, humidity, light, and gas monitoring. Using sensors like DHT11/DHT22, LDR, and ...

The amount of light reaching the LDR from the LED decreases as the pipe is bent, and with a simple divider circuit a voltage can be read by an Arduino.

Key instruments include LDR sensors, Arduino Uno, relay modules, and a power supply system. This project offers a practical solution to improve energy efficiency in offices, suggesting future ...
