I have had trouble with some coding getting several different ones

How do I know witch code is right for my project, Is coding different on a Hero board as compared to Uno board

I've never heard of the Hero but from a quick search it doesn't seem to be compatible with the Arduino.

If it uses the same processor(s) it might work (and it could run the same machine code), but the I/O pins are probably numbered differently and it probably doesn't come with the Arduino bootloader.

Are you referring to this kit?

If so that is apparently a faithful UNO clone which should behave exactly as an Arduino-branded UNO.

You need to explain to us exactly what you are doing if you need assistance. :cold_sweat:
