Basic queuing system/customer calling system

Good day to all you Arduino wizards out there!

Please could i ask for some assistance. I have a retail store with 4 teller points. I wish to build a customer calling system - each cashier would need a button at their till point and then a screen/led number indicator at the front of the queue indicating which till point is open. Perhaps even a "next customer please" chime. Is this easily doable with Arduino?

Apologies if i seem ignorant but it would be my first Arduino project

Welcome to the forum!

“Easily doable” and “first Arduino project” are not good bedfellows but the project as a whole is very doable if you are prepared to take your time and take it step-by-step.

  1. Display a number on a an LED depending on some logic. Very easy, and there are some very large LEDs out there (you only need one seven-segment LED as you only have 4 numbers to display. I don’t have a video or circuit for this but others will undoubtedly show you (or you can search). You can get it all working with a standard small one first.

  2. Trigger the number from each till - could be hard wired or better still remote controlled using one of those 4-channel remote controls you can get for next to nothing on the Internet. In fact I used on in my child’s bedroom light (Youtube video #27, URL in footer of this post) which outputs one of four digital pins depending on the button pressed. Sounds ideal to me!

I’ll see what others have replied but now I must dash.

Many thanks Ralph.
