Result/Analysis
 -As a result, the aim of the development of this project is to combine a digital form and a tone of voice into a voltmeter as well as to provide more accurate reading. The instrument should be a low cost and user friendly product that can be benefited to the engineering sector where appropriate.

-Objective:

• To measure the voltages up to 50V and pronounce the voltage measured through speakers.

• To make the logic probe beeps once in a low tone if the output voltage is low and beeps twice in a higher tone if the output voltage is high.

• To takes multiple samples in succession and calculates the max, min, and mean voltage and speaks the values over a speaker.

• To measure the frequency with a great accuracy from about 10 Hz to 100 kHz and converse the value over a speaker.

-A lack of voltage at a given point may indicate an open circuit or ground. A low or high voltage drop may indicate a high resistance problem like a poor connection.
-If the voltmeter is connected in series, its high resistance would reduce circuit current and can cause a false reading. The false reading is due to the meter changing the circuit by lowering the resistance, which increase the current flow in the circuit. The effect of a voltmeter on the circuit to which it is attached is sometimes is referred as a “loading effect”. The loading effect determined by the total resistance of the circuit in relation to the impedance of the voltmeter.

-The research outcomes will provide some original contributions in developing a new voltmeter and these findings will suggest useful recommendations in establishing the area such as in a technical school and university.

-Benefits:

• More accurate.Do not require to figure out exactly what reading is the needle sitting on in order to get the voltage reading. It takes a precise, computer-generated reading, converse it and displays the reading on screen.

• More sensitive.It has internal buffers, where the ohms per volt figure is meaningless. The typical DVM's have impedances of 10M ohms or more, regardless of the voltage setting.

• User-friendly and more fun for a technical school student.It performs the calculation and displays the reading, rather than relying on a reader's ability to calculate the correct reading. User friendliness makes a digital meter more usable, and less time consuming.

• Speed of reading.In most laboratory application, a speed of one reading per second is satisfactory. However, there are some cases where faster speeds are necessary. Some DVMs are capable of making up to 500 readings per second with 6 digit resolutions and a DC accuracy of 5 ppm and 10 nV sensitivity.

• Range selection.DVMs can be made to have a manual or automatic range selection. Where a large number of measurements having a wide range of random voltages must be made, automatic range selection can be useful feature.

Conclusions
 As a conclusions, the aim and objective is essential in order to achieve what the project capable of doing and with listing it the project will do as what it has plan. The problem statement is the problem that always occur in the industries whether it analog or digital voltmeter and try to solve the problem by implementing it this project and finally each project will have it benefit. This project also have it benefit and the benefit of this project, it hope can
