Spaceship Interface
The spaceship interface is one of the elementary programs in Arduino. For this interface, a power source courses through 3 LED lights into a switch. Upon receiving power, the green LED will begin to glow with the red LED lights emitting no light. When the switch is pressed, the red LEDs will consecutively light up into the green LED, emulating the countdown of a spaceship before takeoff.

Love-O-Meter
The Love-O-Meter is a project featuring the use of a temperature sensor to detect heat. Using a set of formulas, the Arduino will print the temperature once every pre-determined instance. By touching the temperature sensor, it is possible to elevate the temperature of the sensor, which will inherently light up the corresponding LEDs based on the difference between current temperature and the baseline temperature.
