Hello! I am wondering why my arduino board is unable to provide any output voltage on any of the pins when the board is clearly powered (LED indicator is on). Before you ask, yes I used pinmode to configure the pins as outputs, and I checked for shorts all over the circuit. There is also no power going to the 3V pin, and I've tried measuring many different pins to see if it was just one faulty pin. I also tried switching USB ports and switching devices to power the board (via USB-C connector) to see if the issue was the lack of input power. I also tried the general "blink" example sketch and altered it to output to a pin, and it did not work. I do not see any visible damage on the board either. Is there any chance there is something I am missing or should I replace the board (ps the board is getting recognized by my computer properly)
Also, this is my first time using Arduino so there may be steps that I missed in the setup.
Welcome to the forum
Sorry, but I don't understand. The Blink example outputs to a pin as standard. What did you change ?
The blink example used the LED_BUILTIN Pin built into the board, so I changed the code to use one of the GPIO pins.
@matt705 can you post the modified blink code you are trying to redirect to a GPIO pin
We ask you to show your code and connection diagram, as requested in the forum guidelines.
You might want to look at this How to get the best out of this forum before you proceed any further.
We only know what you tell us, and without knowing what you have, we don't stand a chance.
This will tell you how to post code on this forum correctly.
Also a photograph of your setup would help.
Did the simple "not modified" code work?
What IDE version are you using?
Thank you to all who responded, I apologize for the lack of information. I do not have a circuit connected to my arduino at all, I am just measuring voltage from the board with a multimeter. I realize now that the pin headers do not provide a good connection to the board unless they are soldered, this fixed half of my issue, I should be able to figure out the rest from here. Thanks again to everyone and I apologize if I made a mistake posting in this forum.
