Week 7: Arduino and Lights

This week, I got back my laser cut box and I was so excited on how my design came out.
The design that was laser cut.

Furthermore, this week the white group was assigned to the main lab in order to learn how to program an Arduino board. This was my first time actually seeing a computer board up close and I was definitely quite surprised by how it looked. Personally, I thought that it seemed quite fragile and easily breakable. However, it was quite sturdy and it could hold quite a bit of force. Along with the Arduino board, the following things were included: The Arduino packet FabLab provided.

Using the package, we connected power and ground to the board by connecting pins. By doing so it helps “power” and enables the user to correctly use the Arduino board. For example, we connected the pins and linked power and ground together so that later on we could “power” and enable the LED lights to blink and turn on. One of the steps to put together the blinking LED lights.

After assembling all the parts of the hardware, we had to “assemble” the software together and make the LED light blink by coding on the Arduino software. Here is one of the activities that we did:

The Arduino code in which sends a SOS through Morse Code.

This example was coded so that the LED lights would emit a Morse Code for
“SOS.” After coding for the LED lights, we had to add sensors. Personally, the sensor was the hardest part of building the hardware. Because the breadboard was so tiny, it was hard to find empty rows and columns to use for the sensor. However, with some help, I was successfully able to make the LED lights blink when I waved my hand over it. After completing and successfully doing so I felt such a sense of pride because, through my first attempt, I was able to successfully complete such a feat.The completed assembly for the workshop.

This week will be very applicable for our group project. Our group project is going to be a feedback droid in which there will be sensors, so learning how to connect the breadboard to the Arduino board through the pins. The coding as well using the Arduino software was very informative and will help us in the coding for our droid. I am excited to be using such new skills in my future group project. Next week, the white team will be soldering so that the LED lights will fit into the box well.

  1. Hey Odelia,
    I really liked how you incorporated your graphic to fit the hole of the light resistor/sensor. That was very creative and shows different ways of incorporating laser cutting and arduino components. Besides that, your designs look great and your code looks well-purposed. Looking forward to incorporating these into our project.

  2. Hi Odelia,
    Your designs are awesome! I totally love them. My group just had the laser engraving session this week and I thought it was very refreshing and interesting. At first, I also thought the board looked fragile and easily breakable, but thankfully that wasn’t the case since I did apply quite a bit of force when trying to assemble the box. Additionally, I definitely think this will help with our final project droid immensely.

  3. Hi Odelia,
    I really enjoy reading your post. Learning to code with Arduino is definitely a fun and challenging process. I’m glad that it is going to be a good practice with your term project as well. There are a lot of things you can do with Arduino and our team is considering using Arduino in our project as well. Hope you enjoy coding for your project later in the semester!
