How to Connect HC-SR04 to ESP32 safely | STOP Damaging Your ESP32 with 5V Sensors! (Voltage divider)

Are you plugging a 5V Ultrasonic Sensor (HC-SR04) directly into your 3.3V ESP32? STOP! ⚠️ This common mistake can permanently damage your microcontroller's GPIO pins. In this video, I will show you exactly why this happens and how to safely connect a 5V sensor to a 3.3V ESP32 using a simple and cheap Voltage Divider circuit (no logic level converter needed!). We also cover how the sensor works (Trigger & Echo pins), how to power it correctly, and how to fix frustrating errors like getting "0cm" output or Arduino IDE upload timeouts or timeout error. 🛠️ Components Used: ESP32 Development Board HC-SR04 Ultrasonic Sensor Resistors (for the Voltage Divider) Breadboard & Jumper Wires 💡 Quick Troubleshooting Fixes Mentioned: Hold the "BOOT" button on the ESP32 while flashing code. Check your USB cable and select the correct COM Port. Make sure VCC is connected to 5V/VIN, not 3.3V! Update CP210x / CH340 drivers if the port doesn't show up.
