The document presents a project titled 'Keypad Interfaced Zigbee Based Security System', which combines embedded systems with a two-stage security approach using a keypad and Zigbee technology. Key components include the Atmega 16 microcontroller, motor driver IC L293D, and a 16x2 LCD display, with advantages such as enhanced security and lower complexity despite some disadvantages compared to biometric systems. The project overview includes hardware requirements, system functionality, and software needed for implementation.

- 8. ZIGBEE • ZigBee is a IEEE 802.15.4-based specifications for a suite of high-level communication protocols used to create personal area networks with small, low- power digital radios. • It is simpler and less expensive than other wireless personal area networks (WPANs), such as Bluetooth or Wi-Fi. • Uses: Electric Meters, Thermostats, Security Systems, Light Switches, Traffic Management, Projects.
- 9. ZIGBEE Contd… • It has a non standard pin size. • UART interface. Uses tx-rx. • To Program ZigBee use a FTDI UART to USB convertor. • ZigBee uses 3.3 volts. • Its range is 10-100m. Zigbee
- 10. OVERVIEW OF LCD DISPLAY • This can be easily connected with microcontroller and microprocessor • 16x2 Is most popular LCD display • It has 2 rows & 16 columns • LCD has two registers, namely, Command and Data • The command register stores the command instructions given to the LCD • The data register stores the data to be displayed on the LCD LCD Display 16x2
- 11. MOTOR DRIVER IC L293D Motor Driver IC L293D • Motor driver IC L293D is used to provide interface between MCU & Motor • It has two H-bridge driver • Motor driver IC does not amplify the current ; it only acts as a switch. • Output current per channel = 600mA for L293D
- 13. PROTEUS VIEW
- 14. WORKING • Numeric keypad is interfaced with port of the microcontroller. • LCD is used to show the entered password or all the messages we want to show when entered password is correct/wrong. • Authorized user has to enter the security code using zigbee.
- 15. • Controller check the entered password from the password saved in it. • If entered code is correct then user has to verify it through keypad • The password entered through keypad may be same as entered through zigbee or may be different. • When verification is done then motor start rotating which represents the opening of door. WORKING Contd..
- 16. ADVANTAGE • It provide more security as compared to the single stage security system • It easy to use • Less circuit complexity • It based on new technology • Cheaper in cost
- 17. DISADVANTAGE • Biometric security systems are more secure then this system but they are also more costly
- 18. SOFTWARE REQUIRED • Programmers Notepad [WinAVR] • Proteus 8 Professional • XCTU
