A very noob question guys
I have a robotic arm and I want to control it through Bluetooth so I see other people’s circuit and mines it’s a bit different t but the pin layout is the same. So can I just put their code in on my robotic arm it has same servo and pin layout as others.
Maybe. It depends what exactly is "a bit different".
Perhaps if you post your circuit diagram and the one that the code is intended to work with you might get a more definite answer.
