This week, I explored output devices.
There are three connections for an LED strip: 5V, Ground, Data. The data pin can be either analog or digital. I tried to use my breakout board from Week 8, which has a SAMD11C chip, with the FastLED library. This gave me an error, which read that the SAMD11C is not compatible with the library. So, I decided to make a SAMD21E17 breakout board, which it said would be supported.
Then, upon using the same example sketch, I got the same error! Nathan recommended that I use the Adafruit NeoPixel library instead. This still did not work, so I worked backwards. I got rid of the strip and did a simple LED on the same pin to see if the pin was working. This worked. Upon several back and forths, the LED strip started working out of nowhere.
