Can A Variable Resistor Be Used As A Switch at Jean Caldwell blog

Can A Variable Resistor Be Used As A Switch. For example, a volume knob can be a variable resistor. Here is a picture of a variable. For example, a heater switches off automatically when its surroundings are at. It is used in devices where both variable resistance and an on/off switch are required, such as in some power tools and appliances. You'll need to add some circuitry to interpret the output of the photo resistor and control some sort of switching element appropriately. Just use three io pins and switch them between high. This could cause an external component to switch on or off; A variable resistor is the type of resistor which changes the flow of current in a controlled manner by offering a wide range of resistances. A variable resistance can act as a selector button. They can also be used to control the voltage across devices in a circuit too. It can act as a control on the amount of current flowing. A variable resistor that incorporates a switch to turn the circuit on or off. As the resistance increases in the variable resistor the current through the circuit decreases and vice versa.
