Mini Potentiometer for robot control
Widely used for the electronics equipment, it has control function in audio and receiver.
1. Voltage divider
Potentiometer is adjustable resistor ,when you regulate the rotary knob or slide knob,the movable contact was sliding on the resistor.and then the potentiometer’s output terminal will get the potentiometer’s outside voltage and movable arm angle.
2. Rheostat
· The potentiometer as the rheostat,you should connect it as two terminal,then in the travel range of potentiometer,you will get the continuously changeable resistance value.
3. Current controller
When the potentiometer was used as the current controller,the one of selected current output terminal must be slide contact leading out terminal.
