How and on what programmed physical alarm

I hope this question is suitable here, otherwise sorry.

I have an alarm clock ($ 5) that has been programmed for snooze, lighting effects, etc.

As a rule, all these devices, such as a calculator, hi-fi-system (with display), etc. How and in what language did they program them?

Do all of them require a small processor? ... or is there even a small cousin of the processor that is so simple and cheap to make light work?

Can / Can these devices be reprogrammed by us for configuration? What programming language?

I'm really curious.

thank you for your time
