Acknowledgement First I would like to thank god for giving me the strength and ability to complete this project. I would also like to extend my heartfelt gratitude to the following persons who have made the completion of this assignment possible. My Teacher‚ Mr. Harvey‚ for giving me this project as I have learnt many things about The Trans-Atlantic Slave Trade‚ the effects it had on Africa and African arrival into the new world. My Bother‚ who helped me with the collection

Activate a yard light represented by an LED using an LDR. The level of light dected by the LDR should be compared to the value currently set by a linear potentiometer. The ower can vary the potentiometer to vary how dark it needs to be before the yard light turns on. Task 2 Task 2 requires adding complexity by incorporating 2 levels of LED brightness‚ depending on the level of darkness. IF the light level falls just below the potentiometer level the LED shoud

could explain why Britain was the first industrialised economy. They had prime access to natural resources‚ especially coal. Britain was in the midst of an Agricultural revolution‚ which led to a decline in work‚ and an increase in population. Factories began to produce things cheaper because of mass production. This led to a development of a new class of people‚ the middle class. The most prominent factor of mid 19th century Britain being the birthplace of the industrial world is their prime access

Generation" was brought about by the invention of integrated circuits in 1958. Integrated circuits replaced transistors‚ and many computer languages came out in this time. Many more computer companies were born during this time‚ and eventually this led to personal computers for everyday use. Microprocessors introduced the beginning of the "Fourth Generation" and a time where computers were in almost every house. IMPORTANCE OF COMPUTERS In the last decade the role of the computer has changed

LDR Circuit Diagram: Here is the schematic for the circuit: Light Dependent Resistors Light Dependent Resistors (LDR) are also called photoresistors. They are made of high resistance semiconductor material. When light hits the device‚ the photons give electrons energy. This makes them jump into the conductive band and thereby conduct electricity. A photoresistor or light-dependent resistor (LDR) or photocell is a light-controlled variable resistor. The resistance of a photoresistor decreases

Two steadfast and ambitious men led two great countries into the ground with their abuse of power; Rome was led by Caesar and Germany was led by Hitler. Were their actions of ambition abuse of their power? Were they honorable men with honorable actions? Did their powers abused which made them ambitious men? So‚ were Hitler and Caesar honorable men‚ or did their powers make them ambitious? When people are given powers they are not supposed to abuse them‚ but people are supposed to use powers for good
