We have used LDR sensor to build many light controlled applications: The circuit diagram to connect BH1750 Light sensor with Arduino is shown below. I2C communication pins SDA and SCL of BH1750 are ...

We’ll be using this module to detect light or dark and monitor the output of LDR op-amp sensor module using Arduino Serial Monitor. Begin by connecting an LDR with a 10K resistor in a voltage-divider ...

By using this sensor and arduino board we can build a digital magnetic compass which can indicates the direction liken East, West, North or South. In this tutorial we will learn how to connect GY-271 ...

Basically, we are playing here with Arduino and a sensor HCSR04. This is one of the cheapest sensors you can find out there still kind of useful. There are a lot of documentation about how to use it ...

This article will introduce the WisBlock RAK12014 ToF laser ranging sensor module ... In this example, we’ll connect the RAK12014 to the RAK 5005-O base, and the distance measurement and the OLED will ...

First, we'll connect our traffic light sensor to a generic breakout shield we have installed on our Arduino UNO: breakout shields are shields containing banks of analog and digital pins, GND pins ...
