Here is the circuit diagram of Electronic code lock system using 8051 microcontroller. It is very useful at residential places to ensure better safety. This system demonstrates a circuit named ...

Some people think that programs for microcontrollers like the 8051 that have limited program memory must be written in assembly language rather than a high-level language like C. The executable code ...

We used to need SBCs for these projects; modern microcontrollers handle them more easily and inexpensively while being easier to maintain.
