If the value is greater than 700, which means its day or bright, then the relay will not operate and the lights remain OFF. Learn more about relay here and how to connect an AC appliance to relay.

Automatic Light Coding. Arduino Uno is used to compute the logics of the two IR sensors. The circuit is controlled through the software loaded in internal memory of the Arduino. The program ...

We all know about Arduino. It is one of the most popular open source micro controller board which is highly useful for doing DIY projects. This Arduino based 3-Way Traffic Light Controller is a simple ...

Automatically controls street lights based on ambient light levels. Low-cost implementation using readily available materials like cardboard and basic electronic components. Powered by Arduino, making ...

In this project, we will see the Automatic Room Lights using Arduino and PIR Sensor, where the lights in the room will automatically turn ON and OFF by detecting the presence of a human. Such ...

Circuit Diagram. Circuit Diagram for this voice recognition using Arduino is given below. Fritzing part for Arduino 33 BLE was not available, so I used Arduino Nano as both have the same pinout. The ...

Using this pulse, the zero-crossing point can be detected using Arduino. 2. Phase Angle controlling Circuit. After detecting the point of zero crossing, now we have to control the amount of timing for ...

The author’s circuit wired on a breadboard for this purpose is shown in Fig. 1. The circuit diagram of Arduino based flashing light is shown in Fig. 2. The circuit comprises an Arduino Uno board ...

Light sensor Dark sensor. 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 ...
