Potentiometers

• Robots can function because of energy from their power supply
• Power supply delivers the right amount of voltage needed by robots to move
• Without a power supply, robots will not function
• Voltage from the power supply can be divided by a potentiometer
• Potentiometer


  • It is powerful in dividing the amount of voltages that flow in the electric circuit
  • Used in radio, television (TV) receivers for volume control, tone control, linearity control, and even in robots
• Potentiometer


  A three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider
• Potentiometers are commonly used to control electrical devices such as volume controls on audio equipment
• Uses of Potentiometer

  • Rheostat: To use the potentiometer as a rheostat, only two pins are used: one outside pin and the center pin
  • Voltage dividers: To use the potentiometer as a voltage divider, all three pins are connected. One of the outer pins is connected to the GND, the other to VCC, and the middle pin is the voltage output
• Rotary is the most common type of variable resistors or potentiometers
• Linear potentiometers produce a resistance output that varies according to the displacement or position of a slider or wiper
• Potentiometer is used to divide the amount of voltage in the arduino breadboard
• Potentiometer produces a continuously variable voltage output signal proportional to the physical position of the wiper along the track
• Potentiometer provides a way of adjusting electronic circuits to obtain correct outputs
• Potentiometer is rarely used to directly control a significant amount of power, but it is used to adjust the level of analog signals and control inputs for electronic circuits
• When using a potentiometer, connections are made to both ends as well as the wiper. The position of the wiper provides an appropriate output signal which varies between the voltage levels applied to the ends of the resistive track
• Some robots need potentiometers to divide the amount of voltage needed
• Potentiometer is a three-wire resistive device that acts as a voltage divider producing a continuously variable voltage output signal proportional to the physical position of the wiper along the track
• Potentiometer helps in dividing the amount of voltage needed by robots
