    A Plethora Of NE-555 data - NE555 Tutorials Page Page 1 of 19 - - - - - - - - - - - - - - - - Copyright © January 28th 1996 ..... Brought to you by Unitech Electronics Pty. Ltd. Following in the footsteps of the "primitive" but quite successful 4 pin OM802 timer IC manufactured by Philips semiconductor way back in 1969, a new and very innovative IC known as the NE-555 timer IC was released to the masses, being introduced around May 1971 by the then Signetics Corporation, to become known as the NE-555 / SE-555. It was called "The Ubiquitous Timer chip" and was also the very first very mass-produced commercially produced timer IC available at that time.The designers had no real idea what product life it would have, nor how brilliantly successful it would be, lasting well over 25 years still in mass-production today. [1971- 1996 ] The NE-555 would prove to be a " hit " and provide Electronic Engineers, Circuit Designers and a host of "Hobby Tinkerers" with a relatively novel and highly economical timer chip that was indeed very stable at timing all the way up to its maximum timing or oscillating frequency of 200KHz and in a very short time proved to be a very "user-friendly" timer integrated circuit for both simple and complex monostable as well as brilliant astable applications. Invented by a clever Swiss born gentleman by the name of Hans R. Camenzind in 1970, the NE-555 went on to become a legend in the industry, Since this versatile device became commercially available in May 1971, a plethora of highly innovative and very unique and "ever-so-ingenious" circuits has emerged and many circuits have been developed and demonstrated to the "N-th" degree in a variety of reputed "trade-only" journals, professional "Engineering Monthly" Journals as well as the vast numbers of excellent hobbiest publications globally, the likes of SILICON CHIP (SC) and ELEKTOR , Practical Electronics (PE) , Electronics Australia (EA) and Electronics Today International (ETI) to name but just a few.

BIPOLAR TRANSISTOR BIASING practically all modern electronics, and is considered by many to be A very proper biasing of transistor is a very crucial measure one of the greatest inventions of the twentieth century. Transistors are invariably used in tremendous applications but its use is mostly for any transistor operation that decides the performance and as integrated form. The essential usefulness of a transistor comes efficiency of the device. There are many ways of biasing a from its ability to use a small signal applied between one pair of its BJT but the very stable way of biasing is the voltage divider terminals to control a much larger signal at another pair of configuration and hence it is been implemented in our light terminals. This property is called gain. This is the only basic intensity sensing circuit. In this section we discuss on the principle used to make an Optically Operated Circuit.

    EXPERIMENT 7. SCHMITT TRIGGER AND MULTIVIBRATOR CIRCUITS I. Introduction I.I Objectives The purpose of this experiment is to get familiar with different types of Schmitt trigger and multivibrator circuits and their implementations. I.II. Prerequisites You are expected to get familiar with the basics of the Schmitt trigger and multivibrator circuits. You can start reading your lecture notes and the section titled “CMOS Schmitt Trigger Circuits,” from your text book by Thomas A. Demassa and Zack Ciccone (pages 437-439). These pages are the introduction parts, and they explain what basically hysteresis is, and why it may be needed. However, that chapter explains digital Schmitt trigger circuits. What we construct in the laboratory are analog ones. Detailed information on these analog Schmitt trigger circuits and multivibrator circuits can be found in “Microelectronics Circuits” by Adel S. Sedra, Kenneth C. Smith. Reading these two references and completing the preliminary work will help you to understand the topic prior to your actual lab session and also it will help you in interpreting your experiment results.

  • Experiment No: 14 ASTABLE MULTIVIBRATOR USING IC
    Experiment No: 14 ASTABLE MULTIVIBRATOR USING IC 555 AIM To design and set up astable multivibrator of 1000 Hz frequency and 60% duty cycle using IC 555 THEORY IC 555 timer is an analog IC used for generating accurate time delay or oscillations. The entire circuit is usually housed in an 8-pin package as specified in figures 1 & 2 below. A series connection of three resistors inside the IC sets the reference voltage levels to the two 2 1 comparators at V and V , the output of these comparators setting or resetting the flip- 3 CC 3 CC flop unit. The output of the flip-flop circuit is then brought out through an output buffer stage. In the stable state the 푄 output of the flip-flop is high (ie Q low). This makes the output (pin 3) low because of the buffer which basically is an inverter.The flip-flop circuit also operates a transistor inside the IC, the transistor collector usually being driven low to discharge a timing capacitor connected at pin 7. The description of each pin s described below, Pin 1: (Ground): Supply ground is connected to this pin. Pin 2: (Trigger): This pin is used to give the trigger input in monostable multivibrator. When trigger of amplitude greater than (1/3)Vcc is applied to this terminal circuit switches to quasi-stable state. Pin 3: (Output) Pin 4 (Reset): This pin is used to reset the output irrespective of input. A logic low at this pin will reset output. For normal operation pin 4 is connected to Vcc.

  • Title: Clap Switch
    Title: Clap Switch I. Summary A Clap Switch circuit uses a microphone within the circuit to detect noises to turn the LED on. A clap switch circuit can be used in homes and businesses to turn on things such as: lights, TVs, or whatever it is set up to the clap switch. In many cases you can snap your fingers, clap your hands, or even speak to it. In fact, with modern technology, you can use commands to activate a piece/pieces of technology to allow it to turn on/off from anywhere within the room of the Clap Switch. II. Objective Individuals will construct a Clap Switch circuit and gain based knowledge on the 555 timer IC, BC547 Transistor and the condenser microphone. Also, individuals will get to see exactly how you can turn things on by a simply clap, snap, and/or the use of the voice. III. Industry Clap Switches can be installed into businesses and homes to allow individuals to turn lights and a number of technology on or off by using claps, snaps, or his/her voice. Clap Switches gives individuals the ability to remain seated or lying down to turn devices on or off. Also, this device is important to industries because technology is growing at an extreme rate and with the component within the Clap Switch it can help advance technology even more. In today’s world, we use voice control within our mobile devices, as well as, devices like the Echo, Google Home, etc. Within these devices that I previously listed, you can turn on a number of technologies by giving it simple voice commands, which is something that a great number of companies are working on – on a daily basis.
