Update! A new TTGO just arrived and it connects just fine to both computers using both cables! Really strange as the other two TTGO devices have be...

#davee, Thanks Dave for the suggestion, but have looked and there are no noticeable error indications in Device Manager. I'll keep looking!

Well here is a new wrinkle in getting this robot car built. I have two of the TTGO ESP32 devices and when I plug them into a USB port, I get a messag...

@zander I think Bill has mentioned he as had the best luck with solderless breadboards from Jameco Electronics, but you might ask him to verify. I...

@zander I believe there was an interim update to boards and/or libraries that broke analogWrite. Mine was originally working, then when I went to ...

@jeffberk Maybe the old car radio needs more current than the 12v from the ATX power supply can provide. How much current does the ATX power supply...
