It is also commonly known as a \u003cstrong\u003e1M preset potentiometer, trimmer potentiometer, preset resistor, or variable resistor\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eA typical trimpot has \u003cstrong\u003ethree terminals\u003c\/strong\u003e consisting of two ends of the internal resistive track and one adjustable \u003cstrong\u003ewiper terminal\u003c\/strong\u003e. Turning the adjustment screw changes the position of the wiper along the resistive element, allowing the component to operate as either an adjustable resistor or a voltage divider depending on the circuit connection.\u003c\/p\u003e\n\u003cp\u003eThe compact \u003cstrong\u003ethrough-hole PCB design\u003c\/strong\u003e makes the 1M trimpot suitable for electronic circuit boards, prototype PCBs, perfboards, control circuits, testing equipment, and DIY projects. A small screwdriver can be used to adjust the resistance during circuit setup or calibration.\u003c\/p\u003e\n\u003cp\u003eThe high 1MΩ resistance value is particularly useful for \u003cstrong\u003ehigh-impedance circuits, sensor calibration, timer circuits, oscillator circuits, amplifier circuits, comparator circuits, threshold adjustment, reference-voltage adjustment, feedback networks, and signal-conditioning applications\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eIt can also be used in Arduino, ESP32, microcontroller, robotics, and IoT projects when an adjustable analog parameter or voltage-divider input is required.\u003c\/p\u003e\n\u003cp\u003eUnlike a normal panel-mounted potentiometer that is designed for frequent adjustment by the user, a trimpot is generally intended for \u003cstrong\u003eoccasional calibration or internal circuit adjustment\u003c\/strong\u003e.
