This project is built on the STC89C52RC microcontroller, utilizing PWM for speed control. It features voice-controlled mode switching for line tracking, following, obstacle avoidence, and remote control via Bluetooth/Wi-Fi/4G. The system also includes speed measurement with OLED display and data tra...
Data Types and Variables Data types define the storage format and size of data. Common primitive data types in microcontroller C programming include char, int, long, float, and their signed/unsigned variants. Type Conversion Priority: During operations, data types are automatically promoted accordin...
Overview This implementation utilizes the LED driver RAM table within the microcontroller to achieve two distinct driving modes. For breathing light effects, only Mode 1 is applicable: Single Scan using RAM2 table. Mode 1 Operation Softawre Selection: The current COM line (single COM) is selected v...
