learning to do the reverse fold was very challenging at first. It was confused to put together the logic of how the same single column could have valleys and hills but after trying it a few times it became instinctual. Besides that the only other problem I encounter was that the paper I was working on was very thick which meant the folds were harder to make, the trade of being that in the end the paper was much better at holding it's shape
I didn't encounter a ton of problems, but I did have to read some parts of the instructions several times to make sure my understanding was accurate. I did some of the suggested readings on electricity, which were surprisingly insightful and had some great graphics.
Initially I didn't understand what the SIK Guide Code was, where it was or what I was supposed to do with it. Eventually I realized, after reading more carefully, that I just had to click a simple hyperlink.
After that the next hurdle was selecting the correct port. At first it refused to work giving me only two possible ports to select from none of which worked. Not knowing how to proceed I decided to disconnect the Arduino and plug it back in. Luckily upon doing that a third port option appeared and was automatically selected.
After selecting the correct port my LED still refused to light up. So I decided to go back to the beginning and rework all the steps one by one. I realized that I'd placed the LED on backwards, I simply reversed the polarity and immediately the LED lit up
I had no problems on the second experiment.
