Have a little read: ... Electronic Components All electronic circuits consist of combinations of electronic components. The power supply provides the electrical force (V) to 'push' current (A) around a circuit. Electrical components can be grouped into three categories: 1. Input transducers - senses a form of energy and converts it into an electrical signal 2. Processors - this may amplify a current or act as an electronic switch 3. Output transducers - changes an electrical signal into another form of energy Basic Electronic Components Input Components Name How it works LDR A light dependant resistor has a high resistance in the dark and a low resistance in the light. Thermistor This resistor reacts to temperature. They have a low resistance when hot and a high resistance when cold. Moisture Sensor These sensors have a high resistance when dry and a low resistance when wet. This is because water acts as a conductor. It is the water that connects the metal strips. Switch A switch is a device
