PROPELLER CLOCK OBJECTIVE :- In this project‚ our aim is to use PIC or 8051 microcontroller to control a row of LEDs to function it as a clock. ABSTRACT :- The Propeller Clock is an electronic device which has a series of LEDs on board that rotate with the help of a motor to give an illusion of a watching a clock ( Digital or Analogue ). This requires a DC motor which rotates the PCB connected to it with sufficient speed so as to create the illusion. The LEDs are connected to a microcontroller

"Propeller Clock" Mechanically Scanned LED Clock Seven light emitting diodes spin‚ giving the illusion of numbers in the air An Overview: Top View Side View How this clock works: A motor spins the "propeller"‚ and a small microprocessor keeps track of time and changes the pattern on seven LEDs with exact timing to simulate a 7 by 30 array of LEDs. It is an illusion‚ but it works nicely. To build this clock‚ few things are needed‚ including: 1. Skill with motors and mechanical

On Social Theory In Social Work We know where we have been‚ where we are now and where we need to go - but how do we get there? A map. Theory is a map. It notes any number of known landmarks (previously achieved or applied solutions) and obstacles (issues or problems) and gives us direction so that we are able to navigate intelligently and arrive safely (minimal discomfort to all) at our destination (desired outcome/s). Theory is an attempt to explain the unexplained‚ to give title to the untitled

analysis in psychology is that the mind can be scientifically studied by using theories and research models. One theory is the social facilitation theory‚ which is the tendency for people to perform better on simple tasks when they’re in the presence of others than when they are alone. Norman Triplett’s study on this theory in 1989 is believed to be the first of this kind. Triplett first noticed the effect of social facilitation in his research on racing cyclists. Cyclists performed better and

Investigating the effects of changing concentration: iodine clock reaction. Abstract This is an experiment to show the Iodine Clock Reaction. To create a chemical reaction to see how long it takes for solution to change to a dark blue Color. When changing the concentration of the iodide (K1) and adding distill water to make it up to 5cm³ each time. This is to see if the reaction takes less with less concentration or faster with more concentration added to the peroxodisulphatee. So with the solution

The two theories I decided to compare and contrast are Social bonding theory and Social learning theory. Although both are quite similar they both have distinct methods and beliefs in how criminal behavior and activity is developed. Social Bonding theory extracted from the Social Control theory is how an individual is brought and developed into society and how it’s ties to external factors contribute to how the individuals delinquent behavior. Social Learning theory occurs when the individual views

Introduction Genetics is the science that explains the variation and transmission of inherited characteristics from parents to offspring. The basic laws of heredity became popular to science in 1865‚ with the publication of the works of Gregor Mendel‚ the father of genetics. He observed that by breeding pairs of different varieties of peas‚ the offspring resembled one of the parents. This inspired him to continue his work that resulted to more experiments on plants. Before starting this exercise
