Ways to add pins in an arduino I'm making a project for school where I'm using flex sensors and converting that into words on an LCD (similar to the signing glove if you're familiar with that). 
I ran into a problem since the Arduino I'm using doesn't have enough pins for all of my flex sensors and my LCD monitor. 

I'm considering getting another Arduino with more pins but I might not have time to order it since my project is due in a couple of days. I was thinking about connecting two arduinos but I'm not sure if that would work (first year coding/engineering student) Any other suggestions as to how I can create more pins? 

Your input is greatly appreciated!

The Arduino I'm using is a sparkfun redboard (it only has 6 analog pins and a separate place to plug in the LCD monitor which I connected to where it says ISP f you look on the link you will see what I'm talking about SparkFun RedBoard - Programmed with Arduino).

I'm using four flex sensors

LCD:
This can be done with the existing board. LCD can be driven by only with the digital pins. Check the below link for the wiring diagram.

Since there are 6 Analog pins available, all flex sensors can be easily connected.
