Light sensor module connection
Begin by connecting the LDR sensor's VCC pin to the 5V output on the Arduino for power. The module provides two outputs: a digital output (LOW/HIGH) and an analog output. In this tutorial, we will learn how to use an Arduino and an LDR light sensor module to detect and measure the. A LDR Module also known as Light Dependent Resistor or Photoresistor is a device that can detect the intensity of light in the environment. LDRs are widely used in a variety of applications, including power saving systems, smart escalators, smart.
