Abstract

A digital ohmmeter is an electrical instrument that used to measured resistance

in electronics. In this mini project, the task given is to design a digital ohmmeter

by using 8051 Microcontroller Board and external circuit contains chip ADC

0831 and LCD 2x16 characters. The result of resistance value is shown in LCD.

Theory of voltage divider is used to determine the value of resistor measured.

The range of resistor measured is set from 1k Ω to 1MΩ. Program is written

using Keil uVision2 in the form of c program. After the program is compiled, the

program will executed by using 8051 Microcontroller Board. Schematic diagram

and flow chart of this project are included in this report.
