RGB color mode is a color standard in industry. It obtains all kinds of colors by changing the three color channels of red (R), green (G) and blue (B) and their superposition. RGB is one of the most widely used color systems. However, most of the RGB controllers in the market are high-end controllers, which

A DC motor PWM speed controller based on STM32 microprocessor, IR2110 driver chip and photoelectric encoder is introduced. The principle of DC motor speed regulation and the working principle of photoelectric encoder are introduced in detail. According to the overall scheme design, the hardware and software designs of logic signal processing circuit, IR2110 driver circuit,

This design is a project in smart home — Automatic curtains, mainly based on infrared induction and single chip microcomputer control to realize automatic pull of curtain. The article introduces the design scheme as a whole and completes the design of hardware and software of the system. With the maturity of Internet of Things technology,

The traditional PID control algorithm has the advantages of simple algorithm, high control precision and high reliability, which is suitable for the deterministic control system with precise mathematical model. The traditional fuzzy controller has a rough division of the universe. It needs to increase the quantization series appropriately in order to improve the control accuracy,
