Re: course in the making

I would like to see how arduino address make menuconfig. It would be interesting to see how Arduino can make changes to these settings.

Re: Voltage drop on EN pin causing reboots

The following scope capture shows the 3V3 rail and the voltage on EN line : (Green = GPIO34 / Yellow = 3V3)
This statement is confusing. Is the scope capture for the green line showing the EN line, or GPIO34 ?

Re: IO34 & IO35 with Reed Switch & ESP32

Also, why use 2 IO pins when you can use one to do the same thing. Tie REED_NC to +3.3v, and tie REED_NO to GND. From the Com. side of the reed (the side you have going to 10k then to +3.3v) take that to your input pin. Good suggestion, but considering that the reed switch will always be positioned...

Re: IO34 & IO35 with Reed Switch & ESP32

From your schematic, this is not how you want to wire up your pull up resistor. Doing it this way can cause the pins to pick up stray interference because they are floating. Also, why use 2 IO pins when you can use one to do the same thing. Tie REED_NC to +3.3v, and tie REED_NO to GND. From the Com....

Re: pulldown enable blocks

Thanks, however there is no way i can tell by the photo. Does your button have a pullup resistor? It does not look like it.,

Re: Cp2102-ESP32 do I need the 2N2222s ?

Just put a 6 pin header on your board and buy one of these. It will do what you want.
