Hi Paulpaulson, thanks for your reply. I did not get an error code. It is working but sometimes all three servos go, or two, or one. I have tried to understand what Boolean means, it is a variable for true or false. I do not understand it here. I have no idea what those lines mean. I tried Googling it but got nowhere.
I copied this from a previous post and altered some things myself. Just to try to get the timing right. I am happy there.
I might just leave it. I am curious though.
Thanks anyway.
