Resistors are simple passive electronic components that restrict the flow of current and give off heat as a result. The resistance is a fixed value denoted in a unit called Ohms.
Found in almost all circuits the resistor is very useful for limiting current to devices like LED lights or for protecting a microcontroller's input/output pins from too much current.
Adjustable resistors called potentiometers allow the amount of resistance to be varied between zero and the upper limit specified. Smaller potentiometers typically use carbon or fine wire internally to vary the resistance and are used to provide a measureable resistance as an input to a circuit. Too much current through a small potentiometer will damage it.
