How to teach ordinary people technical things?

Question

Electronics

They sent me to a city exhibition or something.
I assembled a robot, I need to make a presentation. But there, in addition to the technicians, there will also be people in other specialties, how can I tell them something to interest them?
I don't think they will understand what RTOS is and why I chose this particular microcontroller, sensor, etc.
Can anyone give me some advice on how to properly present information at such events?

Answer 1

Explain everything with everyday examples, show life stories, help yourself with gestures and charisma, select 2-3 people from the audience and switch your eyes between them.
I understand that it’s hard for you to imagine life stories about RTOS now, so feel free to draw parallels: they say that grandfather used to close his back already in the second garden, but with an implanted microcontroller, he began to process 2 hectares a day like a terminator. I agree, the example is rough, but feel free! Improvise!
Nobody needs your dry speeches.

Answer 2

Only dilute with examples from situations and things understandable to ordinary people.
