Story
In this tutorial video, you'll learn how to physically connect the BH1750 light sensor to your Arduino board and use Arduino code to retrieve luminance values from the sensor in lux units. This knowledge is incredibly useful for various applications, from smart lighting systems to environmental monitoring setups. By following the steps carefully, you'll understand both the hardware setup and the code integration process, allowing you to incorporate the BH1750 sensor seamlessly into your projects.Before reading the remainder, be sure to subscribe and support the channel if you have not!

Step 1-) Physical Connection
For this tutorial, we'll be using an Arduino Nano, but feel free to use any Arduino model you prefer. Just ensure that you map the same four connections for I2C. Keep in mind that different Arduino models may have different pin arrangements, so match all connections appropriately according to your specific board's layout. Additionally, verify that the pinout matches your BH1750 sensor to ensure seamless integration.
Step 2-) Code Arduino IDEGo to Arduino IDE and download the BH1750 library by Christopher Laws. You can download it from the Library Manager.
Next you can open an example file in File > Examples > BH1750 > BH1750testIf you did everything properly you can run this example which incrementally reads lux values from the sensor. Shine a light at your BH1750 and see how it reacts, the lux values should increase accordingly, pretty neat. This code is the building block of projects you can create with this sensor. I hope you got it to work
