HI sir…

Hope you will be fine.I am new commer in your profile.

I want to make this project,would you give me complete circuit diagram and guide me to finish it?

Please sir.

BYE

hi nidhin.k,

hope you will b fine,

Brother how to write this code in proteous?its is in hex file code,would you send me a .c file

and its for pic based?

and 2nd whom you used pic?

i will try you given code .c file test it on mikroC software,after givin.please send me.

thanks alot
