my name is Patrick and I am 15 I am a research student at a high school I am having trouble figuring out what is wrong with my code. But I must admit like most coders do I just copped and pasted most of it so if somebody could help me out that would be great.
and the error messages when i compile : Sketch uses 33228 bytes (103%) of program storage space. Maximum is 32256 bytes.
Global variables use 1721 bytes (84%) of dynamic memory, leaving 327 bytes for local variables. Maximum is 2048 bytes.
Sketch too big; see https://support.arduino.cc/hc/en-us/articles/360013825179 for tips on reducing it.
