Here, we are designing a simple light activated switch circuit using LDR. It can be used in security applications like when there is darkness on the LDR, it stops lighting. The main principle of this ...
Let me introduce another simple microcontroller-based do-it-yourself circuit that detects motion and excites a light source in a flash. The “snooper” here is an ordinary passive infrared (PIR) motion ...
