Light Depend LED Flasher Circuit A light-dependent LED flasher circuit is a simple electronic circuit that flashes an LED (Light Emitting Diode) at a certain frequency using a light-dependent resistor (LDR). The circuit uses the LDR to detect changes in light intensity, which triggers the LED to flash on and off. Here is a simple light-dependent LED flasher circuit Components: LDR (Light Dependent Resistor) LED (Light Emitting Diode) Resistor (1k ohms) Capacitor (47uF) IC (n555) | SR Electric
