This is similar to the other light intensity indicator tutorial. In this tutorial, the 7-segment LED display will be used to display the intensity of the light received by the photo resistor, mapping the light intensity values from 1 to 9.
This is a simple light intensity indicator using a photo-resistor and 3 LEDs. It indicates the amount of light available around the photo-resistor with a range of 3 LEDs. Arduino UNO board will be used in this tutorial.
