Circuit Description:

Circuit of "Interfacing ADC0808 with 8051" is minimal complex which contains all the more associating wire for interfacing gadget to one another. In this circuit we have for the most part utilized AT89s52 as 8051 microcontroller, ADC0808, Potentiometer along with LCD.

A 16x2 LCD is associated with 89s52 microcontroller in 4-piece mode. Control pin RS, RW along with En are legitimately associated with pin P2.0, GND and P2.2. Also, information pin D4-D7 is associated with pins P2.4, P2.5, P2.6 and P2.7 of 89s52. ADC0808 yield pin are legitimately associated with port P1 of AT89s52. Address line pins ADDA, ADDB, AADC are associated at P3.0, P3.1, along with P3.2.

Lager (Address lock empower), SC (Start transformation), EOC (End of change), OE (Output empower) and clock pins are associated at P3.3, P3.4, P3.5, P3.6 and P3.7.

Also, here we have utilized three potentiometers associated at pin 26, 27, and 28 of ADC0808.

A 9 volt battery and a 5 volt voltage controller in particular 7805 are utilized for driving the circuit.
