Many thanks for the reply, I like the idea of the display with the buttons but not sure if its starting to get a bit big and if I box it when im done the buttons are very low down. either way where is best to read how to control these. It says serial but I have also seen I2C, SPI or RS‐232(TTL) and im not sure what the difference with them are or whats best.
As for buttons I would want max 6 so in guessing from my little knowledge I would make some kind of matrix with them?
This is one of thoes ideas ive had and really want to build but i've not touched electronics in depth for many years and having to relearn and as for the arduino that all new
