I’ve just built the Rainbow Cube and checked all the connections but I get nothing. I’m powering it up with 9V and I’m getting power to the Rainbowduino, as can be seen by it lighting up and communicating with the IDE. However, no power seems to be getting to the rest of the kit. I have neither of the base LEDs lighting up. Nor do I read any voltage across the resistors. What should I try next in order to troubleshoot it?
Thanks in advance
