Forum rules and how to ask a question that gets answered

Welcome to the ESP32 Projects forum! This is a place to ask, help and show off your ESP32 and Arduino builds. A few simple rules keep it pleasant for everyone.

Rules

1. Be kind. No insults, no personal attacks, no "just google it". Everyone started with a blinking LED.
2. Stay on topic. One topic, one question. A new question deserves a new topic in the right section.
3. No ads or spam. Links to your own shop, channel or referral programs will be removed. Links to documentation, GitHub and datasheets are always welcome.
4. No piracy. Do not ask for or share cracked software or paid libraries.
5. Safety. If your project touches mains voltage, say so clearly — people will help you do it safely.

How to ask so you get a quick answer

• A specific title: "ESP32 resets when the relay switches on", not "Help!!!".
• Board and toolchain: ESP32 DevKit / C3 / S3, Arduino IDE or PlatformIO, ESP32 core version.
• Wiring: which GPIOs, where the power comes from. You can build the circuit in the simulator and share the link.
• Code as a block, not a screenshot:

void setup() {
  Serial.begin(115200);
}

• The full error text from the serial monitor or the compiler output.
• What you have already tried.

Once your question is solved, press "Mark as solution" on the answer that helped: the next person with the same problem will find it right away.
