Yeah.
and I think a remote control is , as I s mentioned previously , you just have a a very simple chip and the mm the user interface is just done usually by push button and in our case we are using a um a wheel control. So uh uh I was looking basically for that chip , which is uh very very standard , and uh I just looked for the wheel sensor and the standard push button. And um  yeah we can change directly.
Yeah.
In fact I have the number of that element which is very standard for remote control. The push button are usually extremely cheap , but I just have one problem and this is related with the wheel sensor , which seems to be quite expensive.
