“ Infrared remote control technology enables short-range wireless control using infrared light, where the transmitter encodes and sends signals, and the receiver demodulates and decodes them. The NEC protocol is a commonly used standard, which includes frame structures such as lead code, address code, command code, etc., and extended protocols can add data bits. It … Read more

This example is a solution for NEC infrared protocol decoding and LCD display based on the PIC16F877A, written using CCS C Compiler V5.015, and supports Proteus simulation (the compressed package includes the remote control model). Detailed Explanation of NEC Infrared Protocol 1. Protocol Overview The NEC protocol is a widely used infrared remote control protocol … Read more
Infrared is a type of electromagnetic wave with a wavelength longer than that of red light. Since it exceeds the range observable by the human eye, it is invisible to us. However, sensors can detect it, with wavelengths typically ranging from 760nm to 400nm. We can take advantage of this to create an infrared controller. … Read more
