    LPG Pumping Machine Controller

    Posted Oct 12, 2014 By Deepak Gupta
    The requirement of the project was to implement a small PCB that can be attached on to the motor itself. Hence we used the PIC12 microcontroller that has a very small foot print as well as a very low cost. The current sense input determines the load that that motor is experiencing and hence based on the load of the motor and also a internal timer the pumping was to be cut off.

    10 - 100 Micro Amp Constant Current Source

    Posted Oct 05, 2014 By Deepak Gupta
    Analog Section The project has the following sections. 16 Bit DAC A Opamp based Precision constant current source. An instrumentation amplifier based current and voltgae sense. A precision 5V voltage reference. Working When the user sets the required current on the microcontroller, the controller converts the same into an equivalent DAC value and sends it to the…
  • Figure:5 Low Power Audio Amplifier Circuit

    Audio Amplifier Circuit using 555 Timer

    Posted Sep 27, 2014 By Sudheer Gupta
    Conventional methods of audio amplification use high power circuits to drive a loudspeaker for areas like an auditorium or any other hall. However for applications involving use of small loudspeakers for low range requirements, we can meet the requirements by constructing a low power amplifier with a low output current such as 200 mA. In this article we are describing the principle, design and…
  • Figure:6 Digital Stopwatch Circuit Diagram

    Digital Stop Watch Circuit

    Posted Sep 21, 2014 By Sudheer Gupta
    This article describes the principle, design and operation of a digital stopwatch circuit. A digital stopwatch can be a circuit displaying the actual time in minutes, hours and seconds or a circuit displaying the number of clock pulses. Here we design the second type wherein the circuit displays count from 0 to 59, representing a 60 second time interval. In other words here the circuit displays…

    Lamp Life Extender by ZVS (Zero Voltage Switching)

    Posted Sep 10, 2014 By Ravi Kumar
    This project is designed to develop a device to increase the life of incandescent lamps. Incandescent lamps exhibit very low resistance in cold condition due to which it draws high current while switched ON, resulting in fast failure.
  • Figure:8 Circuit Diagram of Boolean Algebra Calculator

    Boolean Algebra Calculator

    Posted Sep 03, 2014 By Sudheer Gupta
    In boolean algebra calculator circuit, we use Boolean algebra simplification methods like the Quine-McCluskey algorithm to simplify the Boolean expression and display the output on the display. It works as a portable calculator to simplify the Boolean expression on the fly. Boolean Algebra Calculator Circuit Diagram: Circuit Explanation: This circuit is a simple 3 variable…

    Thyristor Power Control by IR Remote

    Posted Aug 27, 2014 By Ravi Kumar
    In this project, we use a standard TV remote for speed control of an induction motor such as fans. An IR receiver is interfaced to a microcontroller to read the coded data from the remote to activate the corresponding output with a digital display.
  • Figure:10 Digital Temperature Sensor using Microcontroller Circuit Diagram

    Digital Temperature Sensor using Microcontroller

    Posted Aug 20, 2014 By Sudheer Gupta
    Temperature sensors are widely used in electronic equipment to display the temperature. You can see the digital clock displaying the room temperature value. It is due to the temperatures sensor embedded in it. Generally, temperature value is analog. It is converted to digital value and then it is displayed. This article describes the same converting analog value to digital value. *Circuit…
