Automatic room light controller using ic 4017 pdf

When we build the 10 LEDs running light for a hobby. Often use IC 4017 CMOS-IC. This really neat chip contains a counter and a decoder circuit. That can show a single output pin for each count from 0 to 9. Do not just look at it. You should learn by doing many circuits using 4017. Below! Automatic Room Light Controller with Visitor Counter Desgined using Microcontroller Rajat shah1, Deepak Rasaily2, Tashi Rapden Wangchuk3, Roshan chettri4,Tsheme choden bhutia5 1, 4,5 Diploma of final year Student in Dept. of Electrical&ElectronicsEngineering, CCCT Polytechnic This automatic washroom light controller circuit is based on two IC namely uA741 which work as a comparator and CD4017 which is a CMOS counter/ divider IC. It take clock signal from the clock input and turn on the 10 output in sequence, each time when it receives clock input pulses with few more easily available components. 1 A DIGITAL AUTOMATIC SLIDING DOOR WITH A ROOM LIGHT CONTROL SYSTEM Adamu Murtala Zungeru 1 and Paul Obafemi Abraham-Attah 2 1School of Electrical and Electronic Engineering, University of Nottingham, Jalan Broga, 43500 Semenyih, Selangor Darul Ehsan, Malaysia adamuzungeru@ieee.org 2Department of Electrical and Electronic Engineering, Federal University of Often we see visitor counters at stadium, mall, offices, class rooms etc. How they count the people and turn ON or OFF the light when nobody is inside? Today we are here with automatic room light controller project with bidirectional visitor counter by using Arduino Uno. It is very interesting project for hobbyists and students for fun as well [] Automatic Room light Controller with Visitor Counter (AT89S52) This Project Automatic Room Light Controller with Visitor Counter using Microcontroller is a reliable circuit that takes over the task of controlling the room lights as well us counting number of persons/ visitors in the room very accurately. These circuits can be used for different automatic light sensing projects including automatic night lamp, automatic street light controller, dark sensor circuits, etc. Automatic night lamp circuit using IC 555 and LDR. An automatic night light circuit controls the switching of light by sensing the surrounding light intensity. The post explains a simple automatic PIR controlled fan circuit for school college use, which responds and switches ON only in the presence of a human (students) in the classroom. The idea was requested by Mr. Souren Bhattacharya. "Bidirectional Visitor Counter with Automatic Room Light Controller and Arduino as the master controller" is designed and presented in order to count the visitors of an auditorium, hall, offices, malls, sports venue, etc. The system counts both the entering and exiting visitor of the auditorium or hall or other place, where it is placed. i need C code for automatic room light controller with visitor counter .. anybody will help me ..for this project . long time ago You don't need a microcontroller for it, you can use a counter IC too. Or do the visitors have to pass some kind of baffle gate? automatic room light i have this project called the automatic room light with visitor counter. there are some sites that offers this project base on 8051 microcontroller. however, i want to make this project with arduino uno and i dont know how to start. can you please help me do this? i dont have any schematic either to start wit
