Setting Baud rate, SBUF register, and TI / RI interrupts. 5. IR Remote Controlled Relay
Minimal data structures (C-like)
The AT89C2051 may be decades old, but its simplicity and low cost (often under $2) make it ideal for learning embedded systems fundamentals. The projects listed here cover nearly all microcontroller concepts: GPIO, timers, interrupts, serial communication, multiplexing, and even analog measurement.
Before diving into projects, you need a working programmer and a test circuit.
: Built-in 16-bit timer/counters for precision delays. Serial Port : Fully duplex UART channel for communication.
