create a circuit with an 8051 microcontroller that sensed when an object passed through an infrared receiver’s receive path to automatically turn on lights and count how many times the receive path was blocked. Discussion To complete the project several smaller circuits were needed to be designed and constructed. The project needed a circuit to pulse an infrared LED at 38 kHz‚ a circuit to receive the infrared signal‚ a seven segment LED display circuit‚ an auto-lighting circuit‚ and a programming

determine it base on finding the melting point and observing the Infrared Spectroscopy. Since copper is a hard metal‚ it will most likely bond to an oxygen atom because they are both hard. In the second experiment‚ I also synthesized RuCl2~4DMSO to determine which DMSO atom; Sulfur or Oxygen‚ combines to Ruthenium (III) to be reduced to Ruthenium (II). I was able to determine it based on finding the melting point and observing the Infrared Spectroscopy. Since ruthenium is a soft metal‚ it will most

other things. By looking at the shape of the spectrum of light emitted by a star‚ we can tell something about its average surface temperature. i) If we observe a star’s spectrum and find that the peak power occurs at the border between red and infrared light‚ what is the approximate surface temperature of the star? (in degrees C) - The approximate temperature would be 3767 degrees C ii) If we observe a stars spectrum and find that the peak power occurs at the border between blue

Energy Transformation Conduction‚ convection‚ and radiation are things that exist in our life. Thanks to that stuff we have things like electricity and things to cook too. I am going to explain things about energy transformation. Heat transfer is the way heat moves through matter to change the temperature of other objects. There are three types of heat transfers‚ Conduction‚ Convection‚ and Radiation. The first kind of heat transfer‚ conduction‚ is heat transferring through direct contact of materials

devices via infrared signals and a few via radio signals. Earlier remote controls in the 1970s used ultrasonictones. The remote control code‚ and thus the required remote control device‚ is usually specific to a product line‚ but there are universal remotes‚ which emulate the remote control made for most major brand devices. The main technology used in home remote controls is infrared (IR) light. The signal between a remote control handset and the device it controls consists of pulses of infrared light

headlines regarding “extreme weather events” occurring around the world and here in America left a curiosity about the history and technology used to forecast the Earth’s weather. Around the world meteorologists use technology such as satellites‚ infrared‚ radio‚ and radar transmissions‚ to help determine the most accurate forecast possible. However‚ even with the most advanced technology available‚ no predication is 100% accurate. Captain Robert Fitzroy of Great Britain started a forecasting system

Symbolism through the Short Story The Pedestrian By Ray Bradbury Since the turn of the century‚ new technology has slowly begun to create an anti-social and impersonal society. Take‚ for instance‚ the advancement of the entertainment industry; people’s idea of a social night out is "going to the movies"‚ where there is very limited social interaction. With the advancements of kitchen appliances‚ time is rarely spent with ones family in the kitchen whether it is to cook‚ wash dishes‚ or just socialize

confined to a small portion of the electromagnetic spectrum called visible light. Enhanced spectral range allows the viewer to take advantage of non-visible sources of electromagnetic radiation (such as near-infrared or ultraviolet radiation). Some animals can see using much more of the infrared and/or ultraviolet spectrum than humans. Intensity range: Sufficient intensity range is simply the ability to see with very small quantities of light.[2] Many animals have better night vision than humans
