...When assessing my intelligences, my dominant intelligence was Body/Kinesthetic. I was not surprised by the results, because it is the method that I enjoy the most. In my opinion the results were correct and incorrect at the same time. I say this because I am a practical application or hands-on type of person, but that is just to cement information that I’ve already learned. For instance, when I first learned how to wire a three-way light switch, I used multiple forms of intelligence before I actually got to the hands-on. I used the verbal/linguistic because the instructor was talking out the steps as he progressed through the slide presentation. I also used visual/spatial because he had a slide show with a picture showing exactly what he was saying. In actuality, I already knew how to wire the switch before I even touched it. So, although I do learn by hands-on approach, intelligence is only a backup to two others. It just happens to be the most enjoyable. My scores on the personality section were pretty much what I expected. I know that I am an extrovert (11) mainly because the majority of my life has required me to work as a team. There was always an individual effort, but it was for a desired team result. I also figured that I would score higher for sensing (14) because I am a practical person. In the Corps the motto was “90% of your time will be spent on the 10%”. What that means is, 10% of Marines are the individuals that act without using common sense. ...

...Theoretical Background A.R.A (Attendance and Room Automation), as the title suggest, this project is about automation. In applying creating this project we, the proponents, aim to integrate multiple devices to produce a system that would automate a room as well as attendance checking. But what is automation? According to Merriam-Webster dictionary, automation is “the technique of making an apparatus, a process, or a system operates automatically. The theory of automation states that “there are three building blocks of automation (1) a source of power to perform action, (2) feedback controls, and (3) machine programming.” (http://www.britannica.com/EBchecked/topic/44912/automation/24840/Modern-developments#toc24841) Power source, being a self-running device, it is necessary for it to have its own power source. The feedback control is the sensing part of the system; this will be the one that gathers the input to be processed delivers the output and will run the actuating device. Last would be the machine programming, provided by the proponents for the whole system to run. Theoretical Framework Each of the devices is supported by different theories which we hope we would be able to integrate. A microcontroller “is a small computer on a single IC containing a processor core, memory, and a programmable Input/Output peripheral.” (http://en.wikipedia.org/wiki/Microcontroller) We will be using this device as the brain of the system. We will be using the memory of the IC to encode...

...in India, we use a manual switch to turn the motor ON/OFF which is used to fill the overhead tank. In such cases the switch is turned OFF only after water starts to overflow from the tank. This in most of the cases leads to a lot of water wastage since the water that overflows, flows into the drains. To overcome the issue of water overflowing from the overhead tank, a device can be installed. This device would buzz when the water in the overhead tank is about to overflow, giving the residents enough time to turn the switch OFF. Hence saving lot of water. The device is also capable of displaying the amount of water in the overhead tank through various LED’s. Approach to the Problem: The main requirements of the water level indicator are: • Low power consumption • Simplified result • Compact • Economical The recommended solution to the given issues: • Use of LED’s enables low power consumption and economical • Use of multiple LED’s gives a simplified result • Use of single IC makes the computation less complex Literature Survey IC 4066 The 4066 is a Quad Bilateral Switch that can be used with digital or analog signals.

...ELECTRICAL SYMBOLS – K Hinds Circuit symbols are used in circuit diagrams which show how a circuit is connected together. The actual layout of the components is usually quite different from the circuit diagram. To build a circuit you need a different diagram showing the layout of the parts on stripboard or printed circuit board. Wires and connections Component Circuit Symbol Wire Function of Component To pass current very easily from one part of a circuit to another. A 'blob' should be drawn where wires are connected (joined), but it is sometimes omitted. Wires connected at 'crossroads' should be staggered slightly to form two Tjunctions, as shown on the right. In complex diagrams it is often necessary to draw wires crossing even though they are not connected. I prefer the 'bridge' symbol shown on the right because the simple crossing on the left may be misread as a join where you have forgotten to add a 'blob'! Wires joined Wires not joined Power Supplies Component Cell Circuit Symbol Function of Component Supplies electrical energy. The larger terminal (on the left) is positive (+). A single cell is often called a battery, but strictly a battery is two or more cells joined together. Battery DC supply AC supply Fuse Transformer Earth (Ground) Supplies electrical energy. A battery is more than one cell. The larger terminal (on the left) is positive (+). Supplies electrical energy. DC = Direct Current, always flowing in one direction...

...ELECTRICAL SAFETY Safety in the workplace is job number one for employer and employee. It is especially important for those who install and service electrical system. Electrical safety defines as “Recognizing hazards associated with the use of electrical energy and taking precautions so that hazards do not produce injury or death”. Nothing can replace a worker or loved one that has died or suffered their reparable consequences of an electrical accident. Government statistics shows that electricity cause more than 20,000 fire a year, almost half of all accidental UK house fire. Each year, about 70 people are killed and 350,000 are seriously injured due to an electrical accident in the UK. Modern living has meant we use more and more electrical appliances in the home. For instance, just 20 years ago the average uk home had a hi-fi system and one TV whereas today it is more likely that there are at least two TVs, games console, microwave and computer.so that risk of electricity accidents in the homes are more higher than before. It has seen in the UK that there are lots of people drying their cloths on electrical heater. This is particularly dangerous and could cause electric shock or fire. Heater have ventilation slots to prevent overheating. If this slots are covered up, the appliance could over heat and catch fire. Many time people are drilling the wall to fix nail without knowing what...

...physical characteristics that humans have separate them from other known mammals. Therefore, innovative approach by means or through application of science and technology close the gap that exists between other animals and humans. With that being said, science is a machine that makes life easier to all humans on the planet. It is not surprising to witness humans looking for answers and solutions to all sorts of problem. This is so because humans are fond of using science to make discoveries. As normal as the life itself, the fact that light did not come on is not unusual because light switches sometime malfunction. In a case like the one described above, a person would be more likely to approach a different light switch somewhere in the dwelling and test whether it will work or not. In everyday life, people do not expect things to refer themselves because they were made by humans and their durability depends on how they are use. In many cases, light...

...Which component is better between a Hub and a Switch? A very broad question that can be answered by asking and answering questions like: Will a hub support more bandwidth with multiple pc’s or will a switch? How many connections can each have at a time and can they be stacked? Which is more cost effective? Without these questions you cannot honestly answer the main question. When it comes to bandwidth allocations and how they are supported the switch is generally hands down the better choice. While hubs do support the same amount of bandwidth they share it between machines while a switch dedicates full bandwidth to each machine. To explain hubs better let’s say I have computers A, B, & C. I am on the 'A' computer and wish to send a file to the 'B' computer. C will hear all the talking but will not take action into receiving the file. Each piece of network data that C receives must be inspected by C and after C realizes that it is not for it the data is ignored. So the total bandwidth is shared among the computers. Whatever bandwidth A and B are not using for this file transfer is left for C to use. To sum it up hubs distribute all of the data they receive to all the network devices they are connected to. This is a highly inefficient use of your network bandwidth. However, there is no processing delay created by the hub because the hub, by definition, does no processing. A switch can be considered a 'smart' hub. It will actively look at the traffic it receives and based...

In order to make a clap switch, we have to combine the touch sensor(monostable mode of 555 and the transistorized dark sensor circuits. Whenever there is loud sound produced near the electret condenser mic, pin 2 of 555 gets triggered and it switches on the LED D1. The LED remains on for a definite time determined by R1 and C1. We can adjust the sensitivity of the circuit using a variable resistor in place of fixed resistor R5.
