calibrated. Digital voltmeters necessarily have input amplifiers‚ and‚ like vacuum tube voltmeters‚ generally have a constant input resistance of 10 mega-ohms regardless of set measurement range. This project aims at building a Digital Voltmeter using an 8051 microcontroller. All the data accessed and processed by the microcontroller is the digital data. And thus‚ the usage of an analog-to-digital converter finds its

LCD based voting machine using 8051 microcontroller (AT89C51) Introduction: Electronic voting machine has now replaced the traditional mechanism of voting due to several advantages like security‚ automatic counting etc. This project presents a way to develop an electronic voting machine which displays the count of votes on a 16x2 LCD interface. A user can get his/her vote register through a set of switches (one for each candidate). After every cast of vote‚ the subsequent count can be seen on LCD

The outcome from this lab is to be able to differentiate when to use ohmmeter and voltmeter for the individual circuit. II. Theory Ohm’s Law states that the electric current through a material is directly proportional to the voltage across a piece of material (such as wire) while the resistance is held constant. mathematical
