POTENTIOMETER A potentiometer is a manually adjustable electrical resistor that uses three terminals. It is a simple electro-mechanical transducer. It converts rotary or linear motion from the operator into a change of resistance, and this change is used to control the levels of output. It is … [Read more...]
PHOTORESISTOR or LIGHT DEPENDENT RESISTOR A Light Dependent Resistor (LDR) is a small, round semiconductor device which has a resistance which varies according to the amount of light falling on its surface. Light dependent resistors are used to re-charge a light during different changes in the … [Read more...]
