Implementation of breathing light based on PIC16F877A + Proteus simulation

Preface While learning the PWM module, I saw few posts about the breathing light of PIC microcontroller in the forum, so I tried to do this experiment myself. Because I am learning the CCP module of PIC 16F877A recently, I thought that the PIC microcontroller has an integrated hardware PWM module, and such a good func

Based on 1602 LCD voltage driver applied in proteus simulation

This example uses 1602 driven by 5V voltage, with backlight, can display two lines, 16 characters per line, cannot display Chinese characters, has a built-in ASCII character set library containing 128 characters, only has a parallel interface, no serial interface. Analyzing the timing diagram, we can see that the pro
