The third goes from the middle pin of the potentiometer to the analog pin A0. In the example above, if the potentiometer gives maximum resistance, the voltage drop across the LDR will be minimum. Potentiometers, often known as POTs, are resistors that are used to detect the output signal of electrical instruments such as amplifiers, guitars, and speakers. As you have seen, a potentiometer is a resistor with varied resistances. CN Coterie specializes in full home renovation, electrical, plumbing, carpentry, cabinetry, furniture restoration, OATH/ECB (Office of Administrative Trials and Hearings/Environmental Control Board) violations removal, and DOB (Department of Buildings) violations removal. The first goes from one of the outer pins of the potentiometer to ground. Level up your tech skills and stay ahead of the curve. At the VERY end, potentiometer resistance is zero, and too much current flows - and the LED overheats and might be destroyed. Terminal 3 or the third terminal is the output signal. Figure 2. "is there a wrong way to wire a potentiometer": yes. It is safer to add a small-value fixed resistor (to limit current flow) in series with the potentiometer. The value or resistance decides how much opposition it provides to the flow of current. It only requires two pins, including the middle pin and one side pin.
