Light sensor Dark sensor. Light and dark detection using an LDR. For this project, let’s stick to the LDR sensor module so we can select the light or dark detection by placing jumpers. We’ll be using ...

Correspondingly, turn on an appliance (light bulb), when the light intensity is low (this can be done by covering the surface of the LDR with any object), that is, when the digital values read are in ...

Wouldn’t it be really cool if whenever a room gets dark, a light bulb automatically turns ON and eliminates the darkness? In this very simple project, I am focusing on eliminating darkness. You can ...
