In this tutorial, we will use one such sensor BH1750 Light Sensor Module and interface it with Arduino and show the Lux value over 16x2 LCD.

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.

That's enough for 12 sensors. The ATtiny85 is programmed via an Arduino which allows for devising a smart way of sending the RF data. It can be programmed to send the output as randomized timed ...

The Power Supply schematic includes a 5vdc Sensor regulator. This reduces the load (and heat generated) on the Arduino on-board linear regulator, and also allows more effective input protection by ...

Night Security Light System – Circuit The circuit diagram of the Arduino-based night security light is shown in Fig. 2. It is built around an Arduino Uno board (board1), PIR sensor connected across ...

Figure 1: Schematic of the prototype. A piezo buzzer and a TCS34725 color sensor, mounted on a small breakout board, are connected to an Arduino Nano.
