The DIY STEM Educational Science Kits Circuit of this stepless dimming lamp is composed of NPN transistors, potentiometers, adjustable resistors, LED light-emitting diodes, and other electronic components, relying on potentiometers to adjust the brightness of LED light-emitting diodes. The DIY STEM Educational Science Toy potentiometer is a resistance element with three lead-out terminals, and the resistance value can be adjusted according to a certain change rule. The potentiometer is usually composed of a resistor and a movable brush.
First of all, let's take a look at the potentiometer and the adjustable resistor. The obvious difference between them is that the potentiometer has a higher power efficiency. This Children Small Lamp Toy is installed on the chassis and has an adjustable handle for people to adjust. However, adjustable resistors generally have relatively low power and are generally installed on the circuit board to adjust the current of the circuit, and generally do not adjust after adjustment. In low-power circuits, the three-pin adjustable resistor can also be used as a potentiometer.
