Don’t know if this was already noted, but the schematic doesn’t feed power to the circuit. Might be a reason it doesn’t work for some people!
Thank you for letting me know! I’ll fix that schematic in the eBook and in the members area. We’re currently updating the “Learn ESP32 with Arduino IDE” eBook as we speak and the next version should be available in less than 2 weeks!
I’ll mark this post as “resolved”. Thanks again!
