Modified the code for much better readability:
- Sensors are now in arrays for easy iterations
- Serial printouts are now iterations of the sensor arrays
- LCD Writes are now also done as iterations
- Display output has been modified, it is now a 20x4 display
- Added some more comments
- Added the option to use random data (Uncomment the code to use it!)
These changes reduced the binary size from about 11k to about 9k and reduced the code by around 80 lines.
