+5v Input Power Supply :
Today i will Show you that how to interface 16×2 LCD with 8051 micrcontroller so Let,s start First you should need to Make a proper input Dc power supply for the Micrcontroller Most of the Microcontroller use 5v DC as a input Here we used LM7805 ic which convert a 7.5v to 35v Dc to a constant 5v DC output

Micocontroller pin out :
Connect Pin No 40 and 31 with positive 5v dc 
This is 16×2 LCD which you people can get easily from electronics Market But dont forget to put a 5k Variable resitor between the pin No 3 Vee in 5v with out doing this your Lcd will show black boxes it means that contast is too much high .

Proteus Simulation 
Hardware of the Project it,s successful:
