I already have a soldered Neopixel LED from the bootcamp. It can be a good indicator since I can easily change the color of the light and it should also be able to be turned on and off. And in this case, I want the LED turns blue if there is intense pressure applied on the sensor (indicating the big wind and it can be really cold). On the other hand, the LED should turn red if the pressure is small. There are many challenges. I coulnd't get the code right, and the circuit didn't work out well either. But luckily after help from out TAs I noticed that one of my indicators was wrong. Then things worked out perfectly.
