This idea came to my mind when I saw our lecturers taking the attendance of 100s of students very hardly. We thought we can integrate the RFID based Security System with

DTMF BASED HOME APPLIANCE CONTROL SUBMITTED BY ABSTRACT Traditionally electrical appliances in a home are controlled via switches that regulate the electricity to these devices. As the world gets more and more technologically advanced‚ we find new technology coming in deeper and deeper into our personal lives even at home. Home automation is becoming more and more popular around the world and is becoming a common practice. The process of home automation works by making everything in the house

glance we noticed all the components‚ the zener diode‚ 3 resistors‚ a capacitor‚ 4 diodes‚ a photocell‚ an LED light‚ and something we thought was a transistor. We knew the first thing to do was to identify all of the components and find out the rating for them. We had to use the microscope to determine the identifying numbers on the zener diode‚ the capacitor‚ and the‚ assumed‚ transistor. The zener diode read 1N5242B‚ the capacitor read 334J‚ and the transistor read 9014C. After searching online

experiment 2 our main objective was to understand the analysis of resistors‚ inductors and capacitors in a sine wave circuit. we measured the impedance of the inductor and capacitor using a current sensing resistor. Inductive reactance is the opposition to the flow of current‚ and capacitive reactance is the opposition to the flow of charge. The tools we used for this experiment a pair of resistors‚ an inductor‚ a capacitor‚ dual channel oscilloscope‚ audio oscillator‚ and a digital multimeter. Using the

and get a better understanding. Moreover‚ from this experiment‚ we can understand the principle of this experiment and learn some circuit knowledge. Background/ Theory In the experiment‚ in an LRC circuit‚ a resistor(R)‚ an inductor (L) and a capacitor (C) are required to connect in series. Just like the figure shows. In the experiment‚ we want to calculate the resonance frequency. We know the current will be maximum when the circuit is driven at its resonance frequency. In addition‚ the amplitude

to the negative terminal. The remote wire comes in from the head unit or source of sound to the remote input. When the source turns on‚ power runs from the remote wire to a relay inside that allows power to run through. Power then runs to various capacitors to store up power before running to the inductor that converts the power to usable power for the MOSFETs. As the power runs through the circuit‚ it eventually comes to resistors which slow up the current flow. Sound comes in through the inputs and

other hand‚ Dynamic RAM (DRAM) is typically charged on the capacitor in it. Static RAM holds the data in the flip flop form where it carries each bit of information. It has different technology and memory storage method to Dynamic RAM. The basic difference between Static and Dynamic RAM lies mainly in structure and work principal. 1. Firstly the main difference in the structure varies due to transistor and capacitor number and setting as just three to four transistors are required
