555 and 556 Timer Circuits

Introduction

The 8-pin 555 timer must be one of the most useful ICs ever made and it is used in many projects. With just a few external components it can be used to build many circuits, not all of them involve timing!
A popular version is the NE555 and this is suitable in most cases where a '555 timer' is specified. The 556 is a dual version of the 555 housed in a 14-pin package, the two timers (A and B) share the same power supply pins. The circuit diagrams on this page show a 555, ....etc

ABSTRACT

Point&Connect (P&C) offers an intuitive and resilient device pairing solution on standard mobile phones. Its operation follows the simple sequence of point-and-connect: when a user plans to pair her mobile phone with another device nearby, she makes a simple hand gesture that points her phone towards the intended target. The system will capture the user’s gesture, understand the target selection intention, and complete the device pairing. P&C is intention based, intuitive, and reduces user efforts in device pairing. The ....etc

Hello this is Astika, I am a final year student at the University of Mauritius in the BEng Electronic and Communication Engineering programme and I am currently doing my degree project on Network Security. The aim is to enhance the IDS Snort and making a testbed for network training and simulation. I would really welcome help on how to connect Snort with Matlab and simulate a testbed for the enhanced Snort, and implementing the attacks as well.
Thanks in Advance ....etc
