Arduino Temperature Monitor
For a university group project, we used an Arduino Uno board to create a temperature monitoring system with an alarm. The system allowed users to see current temperature and desired temperature levels (min. and max.) on a programmed LCD display. The temperature settings could be changed using a combination of a potentiometer and buttons and there was an inbuilt alarm using a Piezo buzzer, which would sound if the current temperature were to be outside the bounds of the minimum and maximum temperature settings. This system has many useful applications such as reptile enclosures, where the temperature must be maintained within certain bounds.
