  32. Görüntünün Sürekliliği (Persistence of Vision) Teorisi http://www.engineersgarage.com/microcontroller/8051projects/seven-segment-multiplexing-AT89C51-circuit Humanbrain cannot differentiate between two events occurring at a time difference of less than 0.04 (1/25)sec. Forexample, iftheindividualdigits of a 4 digit 7 seven segmentdisplayaredisplayed one after the other so fast, the human brain cannot detect the difference. Although only one digit is displayed at a time,it appears as a four digit number. http://www.youtube.com/watch?v=IpFqXNPH1NU

  33. Çoğullama (Multiplexing) Multiplexing is a techniquetocontrol morethanone 7 segmentdisplayswith a few IO pins.It is based on having two or more 7 segment displays and connecting them together. (An example of what they would display is 00, 11, 22, 33, 44, 55, 66, 77, 88, 99.)But what we do in this case is control each GND (-) individually which turns it into a multiplexeddisplay. We will switch displays every 0.5mswhich gives us control of each display. It is useful when you are building a project with lots of components and are short of IOpins. Forexample, withoutmultiplexing, drivingtwo 7 segmentdisplaysrequires14 IO pins to control the whole circuitry. On theotherhand, we can control two7 segment displays with 9 IO pinsusingmultiplexing. http://www.instructables.com/id/Arduino-7-segment-countdown-timer/step2/What-is-multiplexing/

  34. PN2222 NPN Transistor (40 V, 0.6 A (600 mA), TO-92) Bipolar Junction Transistors, BJTs, are three-terminal devices. The terminals of a BJT are called the base (B), the collector (C) and the emitter (E). The symbol used to represent anNPN type BJT is shown in Figure a. The physical appearance of a PN2222BJT is shown in Figureb along with the relative locations of the base, collectorand emitter for that BJT. If we apply a voltage to the base of the BJT, current is allowed to flow from the collector to the emitter of the BJT. Typically, the higher the voltage applied to the base of the BJT, the more current flows from the emitter. The BJT can act as a switch; low base voltages turn off the switch (the emitter current is zero) while high base voltages turn the switch on (the emitter current is non-zero). http://www.digilentinc.com/classroom/Electronics101/p1.cfm
