makeasks MAKE Asks: Tricky Troubleshooting
Make: Asks is a new weekly column where we ask you, our readers, for responses to maker-related questions. We hope the column will spark interesting conversation and that we’ll get to know more about each other.

When using an XBee for the first time, I found that if I tried to run the “Hello World” code, I could only get my flashing LED to work if I unplugged one of my indicator LEDs, and vice versa. After going through what I thought was every possible troubleshooting measure, it turned out the culprit was a weak solder joint where the power was coming through. It provided enough juice for just a couple of LEDs, but no more than that. It took a while to figure out but it was one of my most maddening problems to fix.

This week’s question: What was a bug or tricky problem on a project you’ve done, and what did you finally do to figure it out and get it working?

Post your responses in the comments section.
