LDR CONTROL CIRCUIT OPERATION
A circuit which is sensitive to LDR LDR dir.ışıg control circuit, as soon as the light falls on the resistance value drops to very small proportions. In this way, the base terminal of the transistor BC548 is provided to + voltage and transistor arrive comes to insulation. If light falling on the range of ARD ARD then the resistance will rise and the collector-emitter of the transistor conduction current flow by providing reacted LEDs are burned. Thus, our circuit is used to provide light in the darkness.
