The potentiometer is a component widely used in electronic circuits, whether to regulate the voltage of a source, the contrast of an LCD display or as a simple voltage divider.
This is a magnetic induction sensor that detects magnetic materials within a range of up to 3 cm. The magnetic field strength and the detection range are proportional. The output is digital. This m...
This Joystick operates by controlling two potentiometers and a button. Two of the potentiometer inputs refer to the X and Y axes, and the button, when pressed, refers to the Z axis. Therefore, thi...
