Circuit Diagram 3

Advantages: Less time consuming Better than paper work Secured than QR or BAR Codes Limitations: One can give other’s attendance Little bit expensive 4

Why Atmel, not Intel 8051/8086 etc.? Features of 8051: No inbuilt memory No inbuilt ADC Less specific functional pin Less ROM and RAM Old IDE Features of Atmel: Inbuilt EEPROM & Flash memory Inbuilt ADC pins More specific functional pins Enhanced RAM size Higher clock speed More I/O pins Advanced IDE with built-in library 5
