Hey guys whatsup, i am new to this forum and have decided to post due to some difficulties i am having with a current project. Everything was working quite smoothly but the addition of the manual buttons has cause a problem, Whats happens is that now i am only able to get one output, for instance if i cover the light sensor, the roof will close, and nothing else. It stays right there, takign my hand off will make no difference in outputs.
Below is my code, i haven't been coding much before so excuse my code if its a bit noob, also, before i used only if else statements, seeing as most of the code now relies on the outcome of the manual button i decided to use while statements with if else. Below is my code,any help would be greatly appreciated.
