I'm trying to build a circuit as seen below, where a sequencer controls the flashing of some LED sections, and an SPDT switch controls power to either the left or the right section of LEDs.
However, I want the PCB with the switch and power source to be located a distance (~1 meter) from the LEDs and sequencer, and I was wondering if I could use USB to connect them.
To be clear, I am NOT connecting this to any sort of computer or microcontroller, I want to know if it is possible to have a USB cable provide VCC and GND from one circuit to another, and then use D+ and D- to provide/disconnect power to the LEDs via the switch. All voltages would be 5 V, and I can adjust the current draw of the LEDs as necessary.
If this is not possible, is there an existing type of cable that can achieve this (three power leads and a ground), or will I have to solder my own?
