i am trying to develop my own project based on 8051. i am using Fingerprint sensor(R305) , AT89S52 and relay for basic relay on/off. given code is not completed i mean i have not included the relay function because it gives error at initial phase.
i am getting too much errors and actually i am new for this platform so please help mehttps://www.rhydolabz.com/wiki/?p=15770
