Today I built a circuit that changes a lamps colour with only a RGB, 5 resistors, and 2 Photoresistors. The code changes how bright certain colours are.

I created a circuit that will take your temperature and for every 2 degrees above 20.00 turns on a LED with just a temperature sensor, 3 LEDs, and some 220 resistors.

Today I created a circuit that will turn on a LED when it turns on and two others will blink when you push a button with three 220 resistors, one 10k resistor, a button, 3 LEDs, a computer and a breadboard.
Lights!
