Actually for the block diagram i meant to say that do i need any other dvices or ICs to interface with the microctroller for proper functioning of the entire circuit or simply the circuit that you provided will do the work ? if you search Finger print based attendance system with 8051 microcntroller in internet you will find many IC such as Max232 ,and many other used in circuit, do I need all of those things here ?
This the diagram which you will find… do i need these MAX 232, LM 358,or any other external device for my project ? Iwill be using Arduino UNO kit for doing this project
