Potentiometer Connection Potentiometer Circuit Diagram. In this example we are using an a d converter which operates at a maximum input voltage of 5 volt. The position of the wiper on the track is adjusted mechanically by rotating a.
In the experiment connect pin 1 and pin 3 to the 5v gnd of the development board and then read the voltage of pin 2 obtained by the potentiometer through the analog input pin a0 and the range is between 0v to 5v. Therefore no current will go from the collector to the emitter of the transistor. Lm386 is a low voltage audio amplifier and frequently used in battery powered music devices like radios guitars toys etc the gain range is 20 to 200 gain is internally set to 20 without using external component but can be increased to 200 by using resistor and capacitor between pin 1 and 8 or just with a capacitor voltage gain simply means that voltage out is 200 times the voltage in.

The middle and bottom pin are connected. Two 6 volt batteries carbon pencil lead for a mechanical style pencil potentiometer single turn 5 kω to 50 kω linear taper radio shack catalog 271 1714 through 271 1716 potentiometer multi turn 1 kω to 20 kω radio shack catalog 271 342 271 343 900 8583 or 900 8587 through. That there will still be a resistive path for current through the motor. In this example we are using an a d converter which operates at a maximum input voltage of 5 volt.
