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.

Arduino: Monitor sensors with an LCD display and a Keypad.
This project refers to an Arduino sketch which with the help of an external temperature sensor (input device) can control the rotation speed of a DC motor (output device). Also, during the execution of the program, there is dynamic calibration as regards the input values of the temperature sensor.
This project refers to an Arduino sketch that implements a simple fire alarm using a temperature sensor, a piezo speaker and one LED as indicator for deaf-mute cases. The alarm checks every second if there is enough room temperature (via the temperature sensor). If there is enough temperature to consider it a fire burning in that place, then the alarm produces a musical tune with the piezo speaker and lights the LED indicator. Otherwise, both the speaker and the LED indicator remain in state OFF.
