Hi guys,
I am new here and do not have enough information about electronics. I have a question for you:
I need a system including :
1) a Keyboard or any data entry device
2) 150 small tool boxes which 3 LED's are on their door (say red,yellow and green). one for screws, one for nuts and the other for washers.
The problem is that I want the system to work in a way that by entering some codes from the central Keyboard, the relevant LED of the relevant box becomes On. Wiring is impossible so the system should work wireless. and the boxes are too small to uses modems or big devices for data transmission.
Moreover the system cost is also a big deal.
Thank you
Regards,
Mehran
