[quote]QUOTE: <i>Originally posted by dinwitty</i> <br /><br />you have to reverse polarity to the LED's to get green or red, this is the same thing for single LED's with 2 colors in them, one red one green element in reversec connection, put AC on it and you get yellow. <br /> <br />Its one less wire but unless the tortoise hase DPDT capability, you cant do it simply. <br />You would have to drive a relay to DPDT a reverse polarity to the signal. <br />or else an electronic driver circuit.[/quote] <br /> <br />Dinwitty, I must not understand what you're saying, or I didn't explain myself well. My method reverses polarity to the signal very simply -- using the same 2-wire circuit that reverses the polarity to the Tortoise motor (pins 1 and 8). No relay needed.
