Electronic Components

Input Transducers Input transducers are devices that convert a change in physical conditions (for example a thermistor, LDR, or variable resistor) into a change in resistance and/or voltage. This is then processed by a voltage divider circuit. LDR

Thermistor Measures temperature Can measure heat or cold

LDR Measures light (photons)

Variable resistor Can change resistance (up to the maximum setting on the resistor)

Transistor Works as a switch or amplifier Converts analogue Signal at 0.7V to ON FULLY
