Firstly hello!
I'm currently building a panel with 16 LED illuminated switches. The LED's are 12v 25ma and the switches are Push to Make. Im using the switches to select between 16 programs on a lighting controller.
My problem is, I need a circuit that will allow the LED of the selected button to illuminate. But it needs to be cancelled out once another program is selected so only 1 LED is ever illuminated? It's been about 4 years since I did A-Level electronics and i have a few ideas using X-OR gates or by using some form of multiplexer/demultiplexer combination?
Can anyone help and has anyone else designed this circuit?
Many Thanks
Craig
