CERT brief activity

The video was made by one of the active CERT member mr. Sunil Thapa and was presented at the program known as "An engineering exhibition and Basic electronics workshop" at Cosmos College of Management and technology. There were Chairman as a chief guest and HOD , academic HOD, departments lecturers at that program. The video was about brief information what CERT did. n n the link of the video is in       www.youtube.com/watch?v=YFJqaNYI5i0    thanks thanks for visit. we want to do something to others to make everyone life's easier and to make Nepal a developed country by providing technical education to all the students and launching the electronics product in Nepal.

APPLE CO-FOUNDER GREAT STEVE JOBS' INSPIRING STATEMENTS.

Steve Jobs statement from the film Steve Jobs

steve jobs was the co founder of world's most top brand named as APPLE whose all products are famous like iphone, macbook, ipad, ipod, apple watch etc. I am really great fan of him. So i posted this statement here.

"when we grow up, you tend to get told the world is the way that it is your life is just to live your life inside the world and try not ot bash into the walls too much. but thats a very limited life. life can be much broader, once you discover one simple fact. and that is that everything around you that you call life was made up by people that are no smarter than you. and you can change it. you can influence it. you can build your own things, that other people can use. its to shake off this erroneous notion that life is just there, and you are just gonna live in it, versus embrace it. change it . improve it. make your mark upon it. and once you learn that, you ll never be the same again."

computer controlled rgb led with arduino uno R3

Arduino is an open source micro-controller board designed for technical as well as non technical user. School level students to the engineering students and other non technical persons and hobbyists are taking the advantage from the Arduino microcontroller. The today's educational system can be improved by this device and this is fun too. I have posted some simple tutorial about arduino microcontroller with simple projects but today i am going to post a little bit difficult project here. This projects utilizes the serial communication between arduino and computer and the arduino output
 can be controlled by computer. Lets explain slowly.

BASIC ELECTRONICS WORKSHOP, GOING TO BE HELD BY COSMOS ELECTRONICS RESEARCH TEAM.

A very innovative team in Cosmos College named COSMOS ELECTRONICS RESEARCH TEAM (CERT) , led by Dipak Niroula, Denesh Neupane and Yunesh shrestha is going to organize a basic electronics workshop for all the first year students of cosmos college of management and technology, Lalitpur, Nepal.

Automatic Night Lamp Using Arduino

component required. 1. arduino uno 2. light dependent resistor, 3. 15 k resistor 4. 330 ohm resistor 5. jumpers 6. breadboard automatic night lamp is an electronic circuit which turn itself on at night time and turns off at day time. the sensor used here is called ldr. the resistance value of ldr increases in night time and decreases in day time.

First Arduino Project with Program (led blinking)

arduino tutorial first arduino project led blinking. arduino microcontroller board is an open source platform for technical and non technical persons to make and develop electronics project. it is the most popular microcontroller board since it is very easy to use. there are various kind of arduino board. arduino UNO, NANO, MEGA etc are some examples of arduino microcontroller board.
 The microcontroller board contains AVR microcontroller. for example arduino UNO has atmega328

lm324 quad comparator

LM324, LM324A, LM224, LM2902, LM2902V, NCV2902 Single Supply Quad Operational Amplifiers The LM324 series are low−cost, quad operational amplifiers with true differential inputs. They have several distinct advantages over standard operational amplifier types in single supply applications. The quad amplifier can operate at supply voltages as low as 3.0 V or as high as 32 V with quiescent currents about one−fifth of those associated with the MC1741 (on a per amplifier basis). The common mode input range includes the negative supply, thereby eliminating the necessity for external biasing components in many applications. The output voltage range also includes the negative power supply voltage. Features • Short Circuited Protected Outputs • True Differential Input Stage • Single Supply Operation: 3.0 V to 32 V • Low Input Bias Currents: 100 nA Maximum (LM324A) • Four Amplifiers Per Package • Internally Compensated • Common Mode Range Extends to Negative Supply • Industry Standard Pinouts • ESD Clamps on the Inputs Increase Ruggedness without Affecting Device Operation • NCV Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements; AEC this IC can be used in various electronics circuits like voltage comparator, triangular wave generator(pwm), voltage monitor(low voltage check), line following robot etc.
