This challenge was Arduino workshop. I have learned Arduino a little bit before, but catching up how to use this tool again took me a while as it is pretty challenging and I don’t know coding. The interesting part was this board has bluetooth that you can connect with your smartphone, and one of the steps we did was changing the color of LED on the board by selecting a color on the phone. (The photo is just blinking LED because I forgot to take photos later on) Honestly, my board had a port issue and lost connection multiple times and troubleshooting took a long time—it seemed because I use Mac OS—and displaying image on the screen didn’t work out somehow. There were still remaining things that I wanted to try but I couldn’t finish, however now I got the sense of it and want to try them out later and further explore.
