Wireless Door Unlock (TI ZigBee+Accelerometers)

I came across this project by some university students for the TI Ultra low power challenge.
They have used a special wrist watch which contains a TI ZigBee wireless device and accelerometers. They send the unlock code by tapping on the wrist, this tapping is interpreted by the accelerometer, then encrypted by the ZigBee device and transmitted. Another ZigBee device is present inside the door lock, which decodes the encrypted unlock code sent by the watch and then activates the servo to open the lock.

PonyProg 2000 Software for AVR Flash memory

PonyProg is a great software for flash memory programming. It supports a great variety of microcontrollers and other devices. Before using it you should check if your device is supported on the Official PonyProg 2000 Homepage. PonyProg 2000 is constantly updated and new devices are added.

AVR Development boards

A microcontroller Development Board is a generic printed circuit board(PCB), not meant for any specific application. It usually has an interface for programming the microcontroller's flash memory, connectors for the microcontroller's I/O ports, LED banks to show the status of the I/O ports, a reset switch and a serial port or some other comm. port for talking to the outside world. But all this is optional and you can add or remove anything from it depending on your needs or application. Development Boards are very important for hobbyists and small projects.

ISP Flash Memory Programmer for AVR using Parallel port

AVR flash memory programmers are easy to build and one programmer can program a virtually program all series and types of AVR devices. This universal compatibility is because of the ISP (In-System Programmable) feature incorporated in almost all AVR devices.

ISP Flash Memory Programmer for AVR using Serial port

AVR flash memory programmers are easy to build and one programmer can program a virtually program all series and types of AVR devices. This universal compatibility is because of the ISP (In-System Programmable) feature incorporated in almost all AVR devices.

Now there are two three types of Flash memory programmers; Serial, Parallel and USB. I've used all of them so I'll tell you the details about each of them. The software is discussed at the end of the post.
