Learning Arduino

I finally got my Arduino UNO in the mail and began playing with it to learn how to connect LEDs to it and code the Arduino to do what I want it to do. Because I ordered the Arduino UNO starter kit, I got a beginners guide on how to use an Arduino. The guide is pictured below:

The first circuit I made was connecting an LED and learning how to code the Arduino to make the LED blink. The map for the first circuit is pictured below:

Here is how the LED blinks after I set-up everything:

The next circuit I made included an RGB LED, which I will be using in my Iron Man Arc Reactor. For this circuit I had to wire up one RGB LED and run code through the Arduino to make it blink in different colors and then fade between a rainbow of colors. The map for the second circuit is pictured below:

Here is how the RGB LED acts when I wired it up to my Arduino:

The last circuit I decided to try out involved a push button and an LED. I decided to try to get this circuit working because I might be using a push button to change between different patterns that the LEDs light up in. So this circuit was great practice on how to wire up a push button. The map for the third circuit is pictured below:

For this circuit, you have to push one of the buttons to make the LED light up. However, if you push both buttons at the same time, the LED will turn off. Here is the video of this circuit working:

I then decided to go back to the second circuit I did and try to wire up 6 RGB LEDs in parallel. I had to Google how to wire multiple RGB LEDs together but found out it’s pretty easy. Here is the video of the 6 RGB LEDs glowing in the same pattern as they were in the second circuit I made:

After I got 6 RGB LEDs working in parallel, I decided to try to double it up and wire 12 RGB LEDs together. It was a tight fit on the baby breadboard but I finally got all of the RGB LEDs and wires in their correct places. Here is the video of the 12 RGB LEDs glowing in the same pattern as they were in the second circuit I made:

My next goal is to change the code in the second circuit and make the RGB LEDs glow in the patterns and colors that I want. However, thanks to these exercises I have a good grip on how to code my Arduino UNO and how to wire the 22 RGB LEDs I will need to put in my Iron Man Arc Reactor.
