Hi to everyone, I looked for an answer on the forum, but or this topic has not be covered yet or I looked for it in the wrong way.
I need to detect right objects in the right position.
For example, in a chess grid I need to verify that the King is in position B2 and the Queen in E8.
Or let’s say, that the Object A is on the first shelf, while the Object B in the third one.
The system should work just when all the object are in the right position.
I thought to reed switch, but if I can know an object is in place, I cannot verify which one.
I then thought to RFID, but it seems I should have a reader for each position and that could cost more then I thought to.
What will you do to solve this issue?
