In this project, a DHT temp. sensor detects the temprature, relays the information to an LCD, which then displays the degrees. This data is then sent to a battery-powered fan via a relay module, and if the temp is above 75 F, the fan will turn on.

8 LEDs are set-up alongside each other, and an arduino program continously lights up and then fades each LED in sequence. It was cool to do this activity because it allowed me to understand how the LED strip on my wall works!

For this project, a program works with a servo motor and some buttons. When the "open" button is pressed, a LEGO arm attached to the motor rises, and when the "close" button is pressed, the arm lowers. So, overall, it works the same as a mini tollbooth!
