DESIGN OF BOARDS VIEWER SQUAD NUMBER SUBSTITUTION SOCCER PLAYERS BASED MICROCONTROLLER ATmega 16

摘要

The final project aims to get a device in the form of board turnover viewer back number footballer digitally, which its use is more practical than the conventional form. The device is controlled by a microcontroller AT mega IC 16 which is connected to the 3x4 as a menu selector keypad numbers on the system and displayed on the viewer an eight-digit seven segment LED.ud This tool is made in several stages namely, (1) Identification of Needs, (2) Needs Analysis, (3) System Design, (4) Design Hardware, (5) Design Software, (6) Preparation and (7) Testing Tool . Board backs viewer numbers substitute in this digital work is controlled by an IC microcontroller ATmega 16 with control system which is made using C language. Where is the programming of language created using software (Code Vision AVR). The hardware support consists of a series of input / output, a portable power supply using batteries, the display uses seven segment LED display, IC ULN2803 and TIP32 transistors as the driver circuit, as well as a processor ATmega16 microcontroller. Replacement player input or output number of the player is done using the menu button on the keypad 3x4. To find seven segment input / output active players, will be marked with indicator LED flame first.ud After doing the experiment and examination it is known that the hardware has been successfully created using the minimum system microcontroller ATmega16 combined with other supporting instruments. The software has also been successfully created using the C programming language is compiled using AVR CodeVision. Overall this software is able to work in controlling the appearance of player turnover. Performance of "Leaderboard Squad Number Substitution Viewer Football Players Based Microcontroller ATmega 16", overall compliance with a predetermined function, run the viewer program is scanning seven segment, entering input via 3x4 keypad buttons, and displays them in a viewer in the form of LEDs seven segment and reset the display to turn off the board viewer.ud Keywords : boards viewer squad number, ATmega 16, seven segment, 3x4 keypad
