Can a potentiometer detect angle?

Yes, but you need a circuit (a PLC may be of help) to convert the potentiometer output (say 0 V to Vmax) into angles. A conventional potentiometer (linear) powered by a constant voltage power supply will work for angles from 0 to 90 degrees, since the voltage you get will be proportional to the angle sinus, starting from zero up to Vmax @ 90 degrees. For angles from 0 to 180 degrees (or -90... 0... +90 degrees) it will be easier with two power supplies connected in series taking the middle point as zero (Volts). Positive voltages from the potentiometer cursor against zero will be obtained for positive angles and negative voltages for negative angles, but you might need a 360 degrees or multiturn potentiometer. There is the basic idea, the rest is yours...

Does the servo motor contain the servo?

A "servo motor" and a "servo" are the same thing. Servos are constructed from three basic pieces; a motor, a potentiometer (variable resister) that is connected to the output shaft, and a control board. The potentiometer allows the control circuitry to monitor the current angle of the servo motor. The motor, through a series of gears, turns the output shaft and the potentiometer simultaneously. The potentiometer is fed into the servo control circuit and when the control circuit detects that the position is correct, it stops the motor. If the control circuit detects that the angle is not correct, it will turn the motor the correct direction until the angle is correct. Normally a servo is used to control an angular motion of between 0 and 180 degrees. It is not mechanically capable (unless modified) of turning any farther due to the mechanical stop build on to the main output gear.

How many connections for a dc servo motor?

It depends on the particular DC servo motor. At minimum, you need two wires for power, and two wires (one may be shared) for sensor feedback. Often, there are more wires, particularly involving the sensor. I have seen servos with two power connections, five position (quad-tapped potentiometer) connections, and two velocity connections, and that was 35 years ago - today, things might be different - what with digital encoders and such.

What does a potentiometer do?

A potentiometer varies the amount of current through an electrical or electronic circuit. EX: the volume control on your radio is a potentiometer. In today's electronic circuitry, digital circuits that change resistance do the same job as the rotary type control do. They tend to be more accurate.

How servo work?

A servo is basically a regular DC motor, with the output shaft feeding into a potentiometer, which is in turn connected to some control circuitry. The control circuitry compares the output of the pot with a control signal, and makes the motor move so that the output of the pot will match the control signal.

Working principle of servo motor?

Servo motors are geared DC motors with the closed-loop circuitry incorporated within them. The basic configuration of a servo motor composed of a DC motor, gearbox, potentiometer and control circuit.DC motor is used to move a gearbox with a large reduction ratio. The final shaft imposes a force on the external load and simultaneously acts on the axis of the feedback potentiometer. So, the potentiometer senses the position of the axis and sends a corresponding voltage to an operational amplifier. This voltage compared to the input voltage, that determines the desired position of the shaft, producing a voltage in the output of the comparator. This voltage powers the motor such that the shaft moves in the necessary direction to align with the angle that corresponds to the voltage applied to the input.

How do you code an arduino to control a servo on a timer?

You will need a sketch (an arduino program), and you'll need to know the interface from the arduino to the peripheral (servo)

How the servo potentiometer works?

A potentiometer is another name for a variable resister used for voltage dividing. Potentiometers have three tabs on them The two outer most tabs have the full resistance of the device across them. The center tab is connected to the wiper that slides across the surface of the resister. A voltage is applied to the two outside tabs on the potentiometer. A voltage of your choosing will appear across either the left tab to the center wiper tab or from the right tab and the center wiper tab. A potentiometer of this type is used to control the speed output of variable frequency drives. A 10K potentiometer has 10VDC applied across the two outside tabs If the drive sees the full 10 volts it allows the drive to go to full output and the motor will run at full speed. With the potentiometer's center tab wiper at half position a voltage of 5 VDC will appear to the drive. When the drive sees the 5 volts it tells the drive to go to half speed output and the motor will run at half speed. This potentiometer is linear so no matter where the wiper is positioned, the motor speed will follow the potentiometer settings from 1% right up to 100%

How do you increase angle near about 359 in servo wire wound potentiometer?

Use a gear set, or use a multi-turn potentiometer. They also make 360 degree potentiometers for this purpose - they generally have four taps that you can feed out-of-phase reference signals to in order to measure the position. The Link GAT-1 trainer, an older aircraft simulator, used this technology.
