The purpose of the project is to create a thermometer that can be plugged on any free serial port without using any programmable components such as microcontrollers.
The project is using 10 LEDs which are being driven by Arduino to produce change in flashing patterns of LEDs whenever the luminosity level drops below the threshold.
The Atmel AVR microcontroller ATtiny2313 or AT90S2313 is used to build an electronic combination lock known as Code Lock, which will be used for access control.
The project is utilizing cheap dot LEDs to create a big LED with an interface through SPI and can be expandable for multiple digits with only three wires for receiving data from any microcontroller boards.
The wireless FM transmitter project enables a user to speak into the transmitter using a microphone where the voice can be heard on any FM radio within 25ft.
