AVR program memory use too high

I'm using an UNO and get the following:

```
AVR Memory Usage
----------------
Device: atmega328p

Program:   47702 bytes (145.6% Full)
(.text + .data + .bootloader)

Data:       1199 bytes (58.5% Full)
(.data + .bss + .noinit)
```

It compiles to 145.6% and won't fit in memory so it can't be uploaded.
