An 8051 Based Temperature Controlled Fan project

to assemble your code you need an assembler, you can download one from download section. and please do not post in old threads.

hii sir I m going to make TEMERATURE CONTROL FAN for final year and its circuit diagram is shown in below link:

I want to that is this project is working or not? And which software should i use to run the program?? Reply fast sir..

@ kgroup
it is not tested yet
anyhow u can take it as a reference and continue it yourself
in this way u will learn
where u need help u can post here

Can u tell me how to do connection of 4-module seven segment in 40 pin socket??

@ kgroup
connect a,b,c,d,e,f,g of each piece to each other and finally with transistor drivers
common point of the segment is controlled by the transistor
it is called multiplexing
