I have an EL wire project with El Escudo Dos that worked perfectly for months but recently, the status light on the El Escudo board stopped lighting up and it no longer lights up the EL wire. Arduino Uno and 12V inverter are still working, I’ve checked all connections, connected different EL wire, and tried different power supplies/outlets. I am unsure how to verify this with a multimeter, but all my testing points to the El Escudo Dos board as the issue.
Does anyone have further advice on how to troubleshoot? Any help is much appreciated!
