Stair lighting timer

by Hidaia Mahmood Alassouli

Overview

The objective of this project is to design and install an electronics timer circuit for staircase lighting

This is a push-to-on, and auto-OFF circuit. User needs to push the button only ones: to turn the light on. The light will turn automatically OFF after some time, since the switching OFF mechanism is timer based. The "push to on" switch is used here; this should be momentarily pushed to turn the light on. When "push to on" switch is pushed, pin-2 gets a negative pulse, and the timer gets triggered. and the IC1 555 output voltage at pin 3 will be high for certain time period, T=1.1RC, energizing the relay and so closing its contact to provide supply to illuminate the lights for that period. At the end of the time period the IC1 555 output voltage at pin 3 will be low, and so de-energizing the relay and so its contact will open cutting the supply and turning off the lamps

Sc. degree in n Electrical Engineering from Bahrain University by June 1995. I covered most subjects in Electrical Engineering, Computer Engineering and Telecommunications Engineering during my study. My nationality is Palestinian from gaza strip.

I was working also as a computer networking administrator in government computer center at Palestine Ministry of Telecommunication and Information Technology. I worked also as electrical engineer engineer in Bahrain Ministry of Power & Water, Bahrain. I worked also as electrical and telecommunication engineer engineer in Bahrain Telecommunication Company, Batelco.

I had considerable undergraduate teaching experience in several types of courses in many universities. I handled teaching the most important subjects in Electrical and Telecommunication and Computer Engineering. I worked as Assistant Professor in the Engineering Sciences Department Bahrain University, and Assistant Professor in Electrical Engineering Department in Bierzeit University, and Assistant Professor in Electrical Engineering Department in Higher Colleges of Technology in United Arab Emirate, and as Assistant Professor in Computer Science Department inAlaqsa University in Gaza.

I could publish 5 papers in a top-tier journals, and 25 papers in conference proceedings besides a lot of published books in Lulu.com and Amazon book store and many publishing and distribution houses in Egypt and Jordan.
I write many arabic articles concerning anticorruption in the online news websites. I have website that I publish on it all my articles concerning anticorruption: anticorruption.000space.com
