Re: need help why my code
I have a few questions so that I can better understand your project. At the moment it seems to me that only a time control is implemented. - What is the external RTC module used for? If the ESP32 is connected to the Internet, it can get the time from an SNTP server. This makes the use of an external...

Re: need help why my code
While i was rebuilding the circiut in Woki i noticed that you're using GPIOs 6 and 7 . These GPIO's are connected to the SPI FLASH and can not be used! (see https://randomnerdtutorials.com/esp32-pinout-reference-gpios/) I'm wondering that your Devkit exposes these GPIOs !? You never called Serial.be...

Re: Why are GPIOs 34 and 35 always LOW ?
I guess your wiring is wrong GPIOs 34,35,36 and 39 needs external pullup or pulldown resistors. The code to initialize these pins is pinMode(34, INPUT); pinMode(35, INPUT); pinMode(36, INPUT); pinMode(39, INPUT); The code to read these pins is bool gpio_34_state = digitalRead(34); bool gpio_35_state...
