How to draw lighting on a specific object?

Question

Sensors

Good afternoon, colleagues.
Please tell me how to implement this idea:
We are preparing an exhibition and we would like to prepare a stand with a touchscreen (touch panel), there will be a list of our products on the touchscreen, it is necessary that when you click on the product, a certain object on the stand is highlighted. How to do it?

Answer 1

Alternatively, take a Raspberry Pi. On it, raise a Web server with scripts that, when a request is received, would send a unit to a specific GPIO port and zeros to the rest. On the GPIO ports, either LED lighting is hung directly if you don’t need a lot of power, or relay sketch inputs (boards with several relays and transistor switches for them) from Arduino. And as a client, use some typewriter with a browser and a touchscreen instead of a mouse. Naturally, you need to make and configure a network between the client or Malinka (even a cross-over patch cord will work), and power the Malinka (5V not lower than 2A via the MicroUSB port). Well, a microSD card of 8 gigs will be required in order to write a bootable Linux distribution onto it for Malinka.

Answer 2

At the hardware level, this task is solved simply, but with a touchscreen ... I would look at some Smart Home software that allows you to display a list and turn on / off the light.
