This is ciruit diagram of interfacing of LCD with microcontroller 8051 family.
This project was to measure heart beat and to display on LCD.In this post we learn how to interface a LCD with microcontroller 8051, please note that here only circuit diagram is presented in this post. However, more literature about LCD programming, different circuit diagram and example codes in assembly language and c like c51 are given in other posts in this blog. The short summary and link of other post related to LCD interfacing with microcontroller is provided below. for further information please check these.
