The Kitronik Light Activated Switch is an electronic kit that detects ambient brightness and acts as an automated on/off switch for various devices. It uses a phototransistor to sense light levels, controlling an output with a Darlington pair transistor configuration that can handle up to half an amp of current. This kit is ideal for projects like garden lights that turn on automatically at night, drawer alarms, or line following robots.The kit requires soldering and includes a PCB with space to add an LED and current limiting resistor (sold separately).Features: Light detection with a phototransistor Automated on/off switching based on light levels Output current control up to 0.5A via Darlington pair transistors Operating voltage: 3V to 12V Contents: 1 x 1MΩ Potentiometer 2 x BC337 NPN Transistors 1 x Phototransistor 1 x 220Ω Resistor 1 x Light Activated Switch PCB Applications: Automatic garden lighting Drawer alarms Line following robots Specifications: PCB Length: 53mm PCB Width: 25.5mm PCB Component Count: 5 Voltage Nominal: 3V Voltage Range: 3V - 12V Standby Current: 0.12mA This kit requires soldering and does not include an LED or power supply.Note: The LED and resistor are not included and must be selected based on your power supply and desired output.
