Every maker has been there: a project that should work but stubbornly doesn’t. The key to fixing it is staying calm and working systematically.
-
Check power — Is the device actually on? Are voltages correct?
-
Check connections — Loose jumpers or swapped wires are common culprits.
-
Isolate modules — Test one section at a time instead of the whole system.
-
Use tools — A multimeter or logic probe can tell you what’s really happening inside.
And most importantly, take breaks. Fresh eyes often spot what tired ones miss. Debugging isn’t failure — it’s part of the creative process.
