Help required for pin control/state change

[redeemerlang]

I recently purchased and I have followed the instructions and have managed to get the light demo recognised in HA, but cant change states.
is someone able to help me through how to setup state changes via HA to work on a GPIO pin on the board itself?
I'm not a developer, so it's probably outside my skillset. If someone could provide me with some information on how to learn how to do this?
thanks
