Introduction<\/strong><\/p>\n\n\n\n

Hello, I\u2019m a second-year student at Haaga-Helia, named Aliisa. I have no previous experience with robotics, so I started this course as a blank canvas, open to learn anything and everything. I took this course to see if robotics were something I would feel drawn to, and I wanted a course with hands-on approach. My project is LED Matrix Moon Phases.<\/p>\n\n\n\n

Ideas<\/strong><\/p>\n\n\n\n

At the beginning I didn\u2019t have any idea, what exactly I would like to build. Luckily, my classmates helped me come up with some ideas. These ideas included the Useless Box, a mirror which shows the timetables of nearby busses\/trains and simple LEDs that would turn on when an alarm rings. Even though I had a couple of ideas, I didn\u2019t feel too attached to any of them. I got my final project idea from the teacher, who had a list with different projects. I chose \u201cLED Matrix Moon Phases\u201d. I felt drawn to this idea, since it just happened to be Halloween season and a perfect time to do anything related to the moon. LEDs were something I wanted to use from the beginning, so I found this project to be perfect for me.<\/p>\n\n\n\n

What did I need to learn<\/strong><\/p>\n\n\n\n

I had to learn how to work with Arduino, how to build the hardware and get the LED matrix to show the desired images. I began drawing the images shown on the LED matrix and creating the images as binaries and later hexadecimals. Making the images ended up being a step I enjoyed greatly, and I successfully got the images to show on the LED Matrix without bigger problems. Most of my time I used searching how to get code to work in Arduino and testing the code. After spending quite a while on my code, I got it to work and next step for me was to show display the moon phases using the clock data with ESP32.<\/p>\n\n\n\n

Coding and troubleshooting<\/figcaption><\/figure>\n\n\n\n

The outcome<\/strong><\/p>\n\n\n\n

After all the weeks working on my project, I didn\u2019t quite finish it due to multiple outside factors. I still feel like I learned a lot during the course, and I\u2019m happy I got this opportunity to do something out of my comfort zone. Surely I will benefit from the information I gathered on this course, and I might return to finish this project on another course. The course was more work than I expected, but I enjoyed the challenge.<\/p>\n\n\n\n
