IR sensor. LED. Jumper Wires. Working Principle: IR Sensor Operation: The IR sensor emits infrared light from an LED and detects the reflected light with a photodiode. When an object comes within the ...

This project-based on Arduino Uno and IR sensors is used to automatically switch on and switch off a washroom’s light that works on AC mains. Whenever a person enters the washroom, the light bulb (or ...

For this, we need a light sensor to detect the light condition and some circuitry to control the Light sensor. It’s like Dark and light Detector circuit but this time we are using Arduino to get more ...

Controlling an LED with Arduino Using an IR Sensor An Infrared (IR) sensor is a commonly used device for proximity detection and object sensing. When combined with an Arduino and an LED, it can create ...

In this project, we are going to show speed in both analog and digital form.By doing this project, we will also enhance our skills in learning Arduino and Stepper motor since this project involves use ...

For first part, upload IR_decoder.ino code to Arduino. Connect the circuit as shown in Fig. 1. MP3 Vire (21-key) remote was used during testing. Compile and upload the code to Arduino. Now, point the ...

preventing accidents and guaranteeing the safety of pedestrians at night is a major benefit of street lighting, but a large amount of energy is wasted due to the manual operation of the street lights.

While Arduino can provide power to LED light strips, you’ll want to use an external power supply to avoid overloading the Arduino board. Most LED light strips require a voltage between 12V and 24V, ...
