Hey there, I’ve been looking off and on for the past two weeks at why I couldn’t get the right output from my rainbowduino, I’ve tried two different LED, the first one displays 3 red lines
and the second shows a thick red line with a hint of green in the center
So: it’s a duemilenove (I’ve tested without the ethernet board) and all its running is a program to blink LED 13, which it does.
It’s attatched to a rainbowduino 1.11 via
TX - TXD RX - RXD RESET - DTR GRD - GRD 5V - VCC
The switch on the rainbowduino is towards the green plug bit (I’ve tried both sides though), and I think that’s the only thing that could be a variable. I’m a pretty competent C programmer, but the electronics behind all this just baffle me sometimes.
