Today we constructed circuits that made lights light up. These lights were powered by a battery that was attached to the Arduino board. The power of the resistor I used along with the battery was enough power to make the lights light up. One of the lights started smelling bad because I think we added too much power and it started to burn out. We had three different light bulbs of different colors and wanted to make them blink in a sequence. After plugging in the arduino to our computer, we used the program to make the light bulbs blink one after the other.
