Webb5 aug. 2024 · Introduction. LM393 IC-based Automatic Night Light Circuit is a very simple project which can automatically control Light on/off by detecting light and dark. In this project mainly consists of an LM393 Comparator IC and an LDR. The LDR detects light and dark and the LM393 processes the LDR data and provide output. WebbStep 1: Components Required LDR -1 ebay / Amazon Resistor - 10k (x1) Transistor - BC547 (x1) ebay / Amazon 9V Battery and Snap - 1 PCB -1 ebay / Amazon LED -2 Ask Question Step 2: Circuting Place all components on PCB according to Circuit given above. Note: adding a resistor of 330 ohms in series with led improves the lifetime of led.

WebbStep 2: Schematics. Operational amplifier LM358 is in the center of circuit, which works as comparator. Comparator compares voltages on both inputs and if input on non-inverting port (+) is higher, output is set to maximum value (Vcc), but if input on inverting port (-) is higher, output is set to minimum value (GND or 0V in our case). stort adamseple
