| Aug 26, 2015 at 13:12 | comment | added | Wouter van Ooijen | Doing this with 3 wires, either using (ground, power, analog level or digital data) or by charlieplexing (assuming you are talking about 5 single LEDs, not multi-color) is easy. Reduce it to 2 wires and you need data-over-power, which is doable but you should seriously considered if it worth the trouble. | |
| Aug 26, 2015 at 13:04 | comment | added | R Drast | Why can't you use 6 wires? Sprinkler system cable is typically 7 or 9 conductors, can be direct buried, and is dirt cheap. Without going the easy way, you will probably still need more than two wires, a microcontroller will need power, common and the signal lead at least. | |
