CHAPTER 1 INTRODUCTION The word ‘dyslexia’ comes from the Greek ‘dys-‘meaning difficulty with‚ and ‘-lexia’‚ meaning words or language. The discovery of Dyslexia which is a learning difficulty comes from the Greek word meaning “poor with words‚” “poor reading‚” or “a disturbance of the ability to read.” Dyslexia is characterized by difficulty with learning to read fluently and with accurate comprehension despite normal intelligence. This includes difficulty with phonological

3.1 – An Overview of the Project The idea for the Black Box project was inspired to me by seeing the Anti Procrastination Box project found on the web [3]. In this project‚ an Arduino board controls a 5V solenoid and an LCD to keep a box locked for a certain period of time which could be set up by the user using the buttons that are below the LCD. Figure 2 shows a picture of how the box looks like. Inspired by this project‚ I decided to make my own version of the project in which a procedure (rather

2.2 Definition of a Microcontroller Microcontroller‚ as the name suggests‚ are small controllers. They are like single chip computersthat are often embedded into other systems to function as processing/controlling unit. For example‚ the remote control you are using probably has microcontrollers inside that do decodingand other controlling functions. They are also used in automobiles‚ washing machines‚microwave ovens‚ toys ... etc‚ where automation is needed.The key features of microcontrollers include:

ECET 100 – Introduction to Engineering and Computer Technology Homework Assignment #1 Name: Which is larger‚ two million pennies or two hundred single dollar bills? 2‚000‚000 / 100 = 20‚ 000; therefore 2 million pennies is larger or worth more than two hundred single dollar bills. Complete the following‚ showing your work: a. 3x10+3 x 2.5x10+4 (3 x 2.5 = 7.5) x 〖10〗^((3+4)) = 7.5 x 〖10〗^7 b. 1200x10-4 – 1.8x100 .12 x 〖10〗^0 - 1.8 x 〖10〗^0 = - 1.68 x 〖10〗^0 c. 1.2x10+2

Step Down DC to DC Converter Ivana Krezzel T. Almazan and Ruphina G. Gomez Introduction In our world today‚ cellphones‚ and laptops are widely used. For some‚ these things are so important especially for students and employers who work from office. These devices are usually operated with battery. A DC to DC converter is an electronic circuit which converts a source of direct current (DC) from one voltage level to another. DC is not easily being stepped up or down. One of the applications

persecution and murder of six million Jews by the Nazi regime and its collaborators. During this brutal time in history‚ rescuers‚ who were non-Jewish civilians attempted to help Jews and other oppressed groups in spite of the many dangers it put them in. Resistors who were both part of non-Jewish and Jewish groups‚ tried to stunt the progression of the Nazi army. Liberators were soldiers who came to the camps‚ and saved as many people as they could. In an entirety‚ most people remained bystanders out of fear

offset from the stored charge. The capacitor forms a time constant with the resistor load which determines the range of frequencies over which the clamper will be effective. In electronics‚ a clipper is a device designed to prevent the output of a circuit from exceeding a predetermined voltage level without distorting the remaining part of the applied waveform. A clipping circuit consists of linear elements like resistors and non-linear elements like junction diodes or transistors‚ but it does
