Here is my schematic. I am new to this (electronic design and building these projects) so please be kind. The schematic is accurate. I have measured the power supply output and it is just over 12 VDC. I measured the power converter and it is 3.3 - 3.4 VDC. The pin that I connected the converter to ...

I do have a schematic but I need to update it. I will post soon. However, nothing is connected to pin 19 and I don't have any 5v on the board (that I know of). The LED is on when either 5v is applied or USB is connected. But in this case the LED isn't 'on', it is flashing. I haven't been able to ...

The alarm will be triggered by HomeAssistant and I am using ESPHome to develop the code. So far I have breadboarded my experimental circuits which all work properly when I have it ...

What exactly is ESP-IDF referencing? I am running Fedora 43 which uses Python 3.14 and has softlinks in /usr/bin for python and python3 to python3.14. It also has softlinks for python2.7. If I loaded python 3.13 but didn't update the python and python3 softlinks, would ESP-IDF be happy?

Thank you for the answers. I suspected that was the case. However, if I downgrade Python, I make break OS utilities. Can I develop ESP32 utilities manually without ESP-IDF? What does the extension do for me? I have been looking for a framework that allows me to develop rich applications in C ...
