Circuits!

I started planning the circuitboard and soldered the headers. I'm making it modular where I can unplug any of the main components. I'm not going to solder the connections for the ESP8266 until I'm sure that it works. I'm also going to hold off on the 8 channel mux connections because I'm not 100% sure it's working until I have all 8 FSRs plugged into it. If you have just one plugged in, it goes a little weird. I'm not sure if it's advisable to have the S0-S3 pins in the opposite order from the initial examples, but it is easier to solder this way. There is no space to add a level shifter, so if I do alter it to a 5V arduino, I'll have to make a new circuit board.
