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 with increasing incident light intensity; in other

Reading Response: Through the Tunnel——by Doris Lessing Meaning: In the short story Through the Tunnel‚ Jerry and his mother spent their holidays near the sea. Jerry‚ the eleven-year-old English boy‚ was trying to become more independent and be accepted by the local boys so he left the safe beach where his mother stayed and turned to a more dangerous one. The main conflict appears when Jerry was convincing himself to practice holding a longer breath and dive through a long underwater tunnel made

Will Light Rail be Enough? August 25‚ 2009 Will Light Rail Be Enough? With traffic congestion what it is today‚ many cities are looking for solutions to remove single-occupancy vehicles from the roadways and still get people where they need to go. Seattle‚ Washington is no different. According to Sound Transit’s website‚ Light Rail was approved via voters and meant to provide transportation to a minimum of 75‚000 passengers daily in King County‚ run 24 hours a day‚ and remove traffic congestion

LIGHT EMITTING DIODES Light Emitting Diodes are electronic components that use the flow of electrons to excite materials into emitting photons of light. A diode is a basic electronic component that allows electricity to flow one way only. The discovery of "light emitting" diodes we believe was an accident sometime around 1907 when a diode in an early radio transmitter was noticed to glow when in use. Incandescent bulbs use resistance in a filament to impede the flow of electricity‚ heating

The traffic light is one of numerous leading aspects in our lives that we don’t appreciate anymore. The literal definition of the traffic light is a signal that uses red‚ green‚ and amber lights to control traffic. The traffic light is a lifesaving invention in the eyes of many people ever since 1868‚ when it was developed. Who would have predicted that a light could save multiple lives and prevent major accidents from occurring? The traffic light has transformed drastically over time. Currently

MinsCAT Bongabong Campus Smart Street Lights is an automatic light control system which uses sensor‚ arduino and relay as the major components of the system. By using this system manual work are removed and energy consumption and human intervention is also reduced because now-a-days the manually operated street lights are not switched off properly even the sunlight comes and also not switched ON earlier before sunset. MinSCAT Bongabong Campus Smart Street Lights needs no manual operation of switching

usual ride in going home for the weekend. Looking out through our car’s window everything was blurry‚ the surroundings were nothing but blurred images‚ you could only see the distorted colors of infrastructures‚ vehicles‚ stalls‚ and people. Lastly‚ you could only hear the engines of other cars as they pass by. But in a certain moment everything changed‚ there was a moment of pause in the air and the scene was different than before when the light had turned red. The blurred surroundings I have
