Blinking an LED Circuit Using Relays

Electronic Kit School. - This is one way to result the blinking LED light with simple circuit and only need simple and few component like resistors, capacitor, and relays. 

In here we will show you one of the simple blinking an LED circuit using relays as the main component that switch on and off of LED when controlled with resistors and capacitors. The circuit mentioned look like shown in Figure 1 below.

In this time, beside we will show you the circuit, here we also will show you component part and global description about this circuit.

Circuit 

  1. Relay
  2. Capacitor
  3. Resistors
  4. Battery
  5. LED
Description

Circuit like in Figure 1 above show you about the simple blinking an LED circuit using relays. From BuildElectronicCircuits site describe that when you apply power to the above circuit, the battery starts charging the capacitor through resistor R2. After a moment, the relay coil pulls the relay into the other position.

This makes the LED turn ON. Because the capacitor now is charged, it will hold the relay in this position. But the capacitor only has enough energy to keep the electromagnet in the relay powered for a little bit before it’s empty (or discharged).

When the capacitor is out of energy, the relay goes back into its original state and turns the LED OFF again. Then the cycle repeats itself. For this circuit with the above component values I recommend the DS2Y-S-DC5V relay or a similar one.

This article will show you the reviewing of Fundamentals of WiMAX: Understanding Broadband Wireless Networking like book description. The last in this article we also will give you link to take download e-book of Fundamentals of WiMAX: Understanding Broadband Wireless Networking that authored by Jeffrey G. Andrews.

Overview

From Gen.lib.rus.ec describe that this is the eBook version of the printed book. Praise for Fundamentals of WiMAX "This book is one of the most comprehensive books I have reviewed ... it is a must-read for engineers and students planning to remain current or who plan to pursue a career in telecommunications. I have reviewed other publications on WiMAX and have been disappointed. This book is refreshing in that it is clear that the authors have the in-depth technical knowledge and communications skills to deliver a logically laid out publication that has substance to it." –Ron Resnick, President, WiMAX Forum "This is the first book with a great introductory treatment of WiMAX technology. It should be essential reading for all engineers involved in WiMAX. The high-level overview is very useful for those with non-technical background. The introductory sections for OFDM and MIMO technologies are very useful for those with implementation background and some knowledge of communication theory. The chapters covering physical and MAC layers are at the appropriate level of detail. In short, I recommend this book to systems engineers and designers at different layers of the protocol, deployment engineers, and even students who are interested in practical applications of communication theory." –Siavash M. Alamouti, Chief Technology Officer, Mobility Group, Intel "This is a very well-written, easy-to-follow, and comprehensive treatment of WiMAX. It should be of great interest." –Dr. Reinaldo Valenzuela, Director of Wireless Research, Bell Labs "Fundamentals of WiMAX is a comprehensive guide to WiMAX from both industry and academic viewpoints, which is an unusual accomplishment. I recommend it to anyone who is curious about this exciting new standard." –Dr. Teresa Meng, Professor, Stanford University, Founder and Director, Atheros Communications "Andrews, Ghosh, and Muhamed have provided a clear, concise, and well-written text on 802.16e/WiMAX. The book provides both the breadth and depth to make sense of the highly complicated 802.16e standard. I would recommend this book to both development engineers and technical managers who want an understating of WiMAX and insight into 4G modems in general." –Paul Struhsaker, VP of Engineering, Chipset platforms, Motorola Mobile Device Business Unit, former vice chair of IEEE 802.16 working group "Fundamentals of WiMAX is written in an easy-to-understand tutorial fashion. The chapter on multiple antenna techniques is a very clear summary of this important technology and nicely organizes the vast number of different proposed techniques into a simple-to-understand framework." –Dr. Ender Ayanoglu, Professor, University of California, Irvine, Editor-in-Chief, IEEE Transactions on Communications "Fundamentals of WiMAX is a comprehensive examination of the 802.16/WiMAX standard and discusses how to design, develop, and deploy equipment for this wireless communication standard. It provides both insightful overviews for those wanting to know what WiMAX is about and comprehensive, in-depth chapters on technical details of the standard, including the coding and modulation, signal processing methods, Multiple-Input Multiple-Output (MIMO) channels, medium access control, mobility issues, link-layer performance, and system-level performance.

555 Timer Circuit using LM324 and 7404 IC

Electronic Kit School. - Maybe you are usually using the popular time IC like LM555 in this time. But, do you know the internal block diagram of this 555 timer IC look like? Yes, when you want to know more about the internal circuit diagram of 555 timer IC you should read this article. 

When you using Proteus software, you can re draw the internal circuit of 555 timer IC look like shown in Figure 1 below. The internal diagram of this IC need some component like IC Lm324, RS Latch 7404 IC and others component.

In this time, beside we will show you the circuit, here we also will show you component part and global description about this circuit.

Circuit 

  1. Resistors
  2. LM324 IC
  3. RS Latch
  4. 7404 IC
  5. Transistor
Description

Circuit like in Figure 1 above show you about the internal circuit diagram of 555 timer IC using the main LM324 and 7404 IC. From Circuitstoday site describe that 555-Timer is one of the most popular and mostly used ICs. It best suits for timing/timekeeping related circuits. It consists of two operational amplifiers operated in an open loop or comparator mode, RS Latch with additional Reset input, a discharge transistor, an inverting buffer and an amplifier in the output stage. It has a voltage divider circuit with three 5K Ohm resistors in series. 556 is a dual timer IC. 

The Upper comparator-UC is a Non-Inverting comparator, compares the input signal with 2/3Vcc and Lower comparator-LC is an Inverting comparator, compares input with 1/3 Vcc. The output of UC is given as R input of RS Latch and output of LC is given as S input of RS Latch. The RS Latch has an external Reset input which provides the option to reset the output instantaneously. The inverted output of Latch turns ON/OFF the discharge transistor. Inverting Buffer in the output stage inverts the output of Latch and drives the load.
