In this project we are making a Light Sensor using LDR with Arduino to control a light bulb/CFL as per light condition of the room or outside area.

Learn to create a simple light-following robot using Arduino, LDR sensors, and an MX1508 motor driver. This beginner-friendly project includes detailed instructions, components list, and coding ...

The circuit of Arduino-based shadow alarm is shown in Fig. 1. It consists of an Arduino board, power supply, light-dependent resistor (LDR) sensor, buzzer, relay driver and a few other components.

Discover the power of Arduino in physics classes! Learn how to build low-cost experimental setups using Arduino boards and peripherals. Explore the benefits of data acquisition and compare results ...

The connection of SHT15 with Arduino is useful for thermostat projects that are often requiring some kind of humidity and temperature sensor.

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 ...
