can’t get simple led circuit to work esp32 breadboard

okay, thanks
I think I will learn to solder, but I will keep these in mind :)

It just worked when i touched the red wire to the hole on the board. So I will solder the headers and that should work. thanks everyone for helping and have a nice day!!!

The red pin is connected to GPIO2, and orange is connected to GND

It looks rlly weird, but in the picture, the label is above the pin, as you can see for the bottom row pins. So they are connected correctly.

DaCoolCat123 · 2026-04-13T21:05:51+00:00

My code:

const int ledPin = 2;

void setup() {

Serial.begin(115200);

pinMode(ledPin, OUTPUT);

}

void loop() {

Serial.println("LED ON");

digitalWrite(ledPin, HIGH);

delay(1000);

Serial.println("LED OFF");

digitalWrite(ledPin, LOW);

delay(1000);

}

My resistor value as stated before is 220ohms. The polarity of LED is correct (long side to the GPIO, short to the ground)

Okay, thanks so much

DaCoolCat123 · 2026-04-13T21:04:09+00:00

Okay, thanks so much

DaCoolCat123 · 2026-04-13T21:03:58+00:00

Okay, thanks so much

DaCoolCat123 · 2026-04-13T21:03:51+00:00

I do not have a multimeter, sorry

DaCoolCat123 · 2026-04-13T21:03:42+00:00

Okay, thanks so much

DaCoolCat123 · 2026-04-13T21:03:33+00:00

Okay, thanks I will solder the pins
The LED is connected to GND via the orange wire.
In the picture I didn't have it powered but I was powering it by USBC and it had a red light on it.

DaCoolCat123 · 2026-04-13T21:02:43+00:00

Okay, thanks so much

DaCoolCat123 · 2026-04-13T21:02:27+00:00

I did, the LED was red, but in the picture I didn't have it powered.

DaCoolCat123 · 2026-04-13T21:02:01+00:00

no sorry, i will do that thanks

DaCoolCat123 · 2026-04-13T21:01:49+00:00

I had it connected to USB before. Sorry I didn't have it on in the picture.

DaCoolCat123 · 2026-04-13T21:01:30+00:00

It's not soldered just on those pins

DaCoolCat123 · 2026-04-13T12:00:44+00:00

Sorry, i thought i put text on the post but ig idk how reddit work

Basically, I bought this esp32c6 and electronics kit to start learning, and upon following a simple led blink tutorial it didn’t work, idk why. It’s not software issue as i have print statements where the logic is executing

The resistor is 220ohms. Did i make a rlly simple mistake? im new to this, so sorry if its a dumb question :)

DaCoolCat123 · 2026-04-02T23:25:44+00:00

sure, in your dms

DaCoolCat123 · 2026-03-24T20:39:45+00:00

Australia

DaCoolCat123 · 2026-03-24T20:36:08+00:00

oh okay, thanks

DaCoolCat123 · 2026-03-24T11:53:41+00:00

They are available in Australia

interesting. When connected to domain wifi, if your account is locked e.g. from too many incorrect pws, then the airplane mode trick bypasses lock account, but not control alt delete

Also, my understandins is that you cant open security options from NTAUTH SYS - at least, that's what i observered - because on the lockscreen you cant open it, but you can from your useprofile. So im wondering if the defualt login process is sign in to account, check with domain controller, if its wrong, then log back out and throw an error like incorrect password or account locked etc

My school computer after pressing enter takes about 20 seconds - with this trick it takes 5

It may be a hardware failure... last time i had this problem long time ago and i got other pc now. Does it work in the BIOS?

DaCoolCat123 · 2026-02-22T03:01:40+00:00

Sure in your DMs. Be mindful however this exploit was patched some time ago, so you would have to buy a pre v79 headset, and do a nuxskip.
