In this document, the researcher will discuss all the components that will be on the board as well as the software of the microcontroller. The heart of the analysis will be dependent upon the IR remote Controller that involves a transmitter and a receiver circuit operation based on using infrared red rays as a medium of a wireless communication. As such, the device is used for all sorts of electronic devices like televisions air conditioners. The document is intended to capture and convey the significant design decisions which have been made in preparation for the development of the system being discussed in this document.
The first process of the system will be the starter mechanism that is made available to the user via the buttons. When the button is pressed, the signal leads up the wire to the PIC. Once there, it is then translated via the logical inputs and given to the microchip unit through the diodes. This output signal is served to the IR LED’s through the current limitation resistors; where the electrical signal is changed to an optical signal. At this point, the motor will start. There are three additional switches which are designed to alternate between fan speeds.
The microcontroller is a device that connects to the computer PC. It is incorporated into the electronic board and contains a memory, processor core, and a programmable input/output. This is therefore used to program the PIC of the remote and the receiver by use of the assembly language.
The IR Receiver is to receive the infrared (IR). IR receiver detects infrared light that is being projected from the transmitter. By using an infrared signal to maintain a charged capacitor, this in turn keeps the run relay ready.
The motor itself is the machine that converts electrical energy into mechanical ability to complete the work; for instance, the electric motors used to run ...Download file to see next pagesRead More

Fan fiction story

...Teacher Fan Fiction: Battleship In the movie Battleship, the aliens came here angry and ready to invade and destroy us. It did not show any initial meeting between mankind and alien before the attack in the pacific rim. The movie is also considered a cliche and almost predictable because mankind always win in the end albeit started as an underdog. What if there was an initial meeting with the alien and we lost the battle? That would make the story more interesting. It would also be interesting if the story will center on the scientist since it is a sci-fi movie instead of Lieutenant Alex Hopper. First chapter: The first coming Who would have thought that life beyond our planet and solar system exists? Since time...

Wireless networking

...Wireless computer networking manual Networking is the linking of two or more computing devices together with or without cables for the purpose of sharing data. Networks are built with a mix of computer hardware and computer software. Networking of computers can be accomplished using cables or wires and also without using any wires. The communication language used by computers when it is networked is called protocol. Networks often use multiple protocols based on the usage or purpose of networking is being used. Popular protocols include TCP/IP (Transmission Control Protocol and Internet Protocol), the most common protocol found on the Internet and in home networks Networking can be of different types like; Local Area...

Wireless

...A site survey begins with the physical layer, identifying whether access to the internet exists, and the location of devices needing access. Wired access to the internet is necessary whether that is through a T1 line or a cable modem. In a residence, it comes into the house as an Ethernet hub offering up DSL, along with cable television for instance. The cost for high-speed residential DSL, bundled with a phone line from AT&T runs about $60 a month, with no cable television reception. A wireless router is then connected to the wired connection, which then creates the data layer, such as TCP, so that an IP address can be assigned. Each device on the network must also have a wireless network card in order...

Idea of Being A Fan

...Idea of Being a Fan This discussion is regarding the intrinsic value a fan possesses within our culture, as well as implications as having an identity within society. I myself, being a big fan of music, have been a fan of many musical bands. My passion for music did lead me on to pick up a musical instrument, namely the bass guitar. There are various advantages to being a fan. Most of these are mainly social, where there are daily interactions with like minded people, who share the same beliefs. Fans have been generally been known to be those people who follow the activities of other famous people. However, fans in reality play a much deeper role, since they are placed as a great resource within the retail outlet sector... , and are...

...up a network system. These physical media are the most reliable for message sending, and they do provide faster data communication through high speed transfer of signals over long distances. Examples include coaxial cable, twisted pair cable and the fiber optic. The unbound media literally use the wireless connections and the transmission done via electronic waves (Odom W., Healy R., and Donohue D., 2010). Data Communication Protocols are a combination of both hardware and software standards that are established to effectively govern data transmission between computers. I.e., TCP/IP is a collection of different communication protocols based on IP and TCP. The TCP (Transmission Control Protocols) is applied in the...
