Arduino: Valuation calculator of infix mathematical expressions.
September 18, 2010
This project refers to an Arduino sketch that implements a calculator which valuates infix mathematical expressions using appropriate algorithms and data structures. The mathematical expressions are given through the USB port, while the valuation and presentation of results is done by Arduino. The results are displayed in an appropriate LCD display.

This project refers to an Arduino sketch which – with the help of a system VRBot, a basic keyboard, an RFID reader and a piezo speaker – can implement a Security Access Control with Multi-Factor Authentication.
The system comprises a security level associated with typing a password (something I know), a security level associated with the use of an RFID tag (something I have) and a security level associated with the recognition of a voice message password (something I am).
Arduino: Monitor sensors with an LCD display and a Keypad.
August 16, 2010
This project refers to an Arduino sketch which uses an LCD display (as output device) with in-built elementary Keypad (as input device) to display information from sensors. In this project, there are temperature, light and motion sensors. If we want to check the value of one of the sensors, we can do it via the keypad onto the LCD screen. We can choose the sensor of interest using the keys UP and DOWN.
