LED Digital Information Transmitter
Digital information transmission is a broadly applied technology nowadays. However, demonstrational instrument for such technology still lacks. Our motivation is to construct an information transmitter that every compartment of the system can be displayed separately.
In order to make the system illustrative, we use LED light and control its blink with a series of high and low voltage corresponding to a series of binary code. The code we designed covers 52 letters including capital ones and other commonly used punctuations. The graph on the left indicates the voltage output of the silicon detector when exposed to the LED blinks. The system can easily transmit a whole passage.
