Looking to see if what I’m thinking is possible... I want to design a system similar to that in a bank with visual and audio prompts to the next available cashier. It would be a single queue, with multiple serving positions, so each operator would have their own button, which would simply call the person to that operators position... perhaps with a visual number display on that position, and an audio message at the queue head indicating which position to go to.
In simple terms, I’m thinking of a main monitor/tv screen at the queue head, which could possibly have advertising, and would indicate a free position number, and each teller would have a button and a position number indicator... the application might have between 2 and 15 positions.
Is this possible with a raspberry pi, and if so, would it be difficult?
