This week we got introduced to arduino, and like the first week, everything was so new to me and before I jumped on connecting wires, I was worried and stressed about how things work. After reading all the related information about the digital input&output, programing terms, setting up arduino, and actually connecting wires, led lights and button, I realized it was not that hard. What a torturous and sweet learning experience.
I followed the lab instructions, which is push the button, one led lights up and release the button, the other lights up. However, only one lighted up for mine. I checked all the wires, codes and couldn't figured out which made me a bit frustrated. But I'm glad at least I understand how it works theoretically.
