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 ...

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 so, I agree, ...

Connect the sound sensor to the A0 port. Please beware that in both ports, the GND and 3.3V pins match with the GND and 3.3V pins in both the LED bar and the sensor. This project can be modified to ...

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 ...
