Microcontrollers & Electronics covers Arduino, ESP32, Raspberry Pi, circuit design, soldering, sensors, and embedded systems.

Posting Rules:

• Specify your hardware. Include microcontroller model, voltage levels, and any shields/modules involved.
  
• Use [code] tags for firmware/code snippets.
  
• Post schematics or wiring diagrams when asking about circuit issues. A photo of your breadboard is also helpful.
  
• State what you have measured. Include oscilloscope traces, multimeter readings, or serial output when debugging.
  
• Safety first. Do not encourage or share designs that violate electrical safety standards. Mains voltage projects require appropriate warnings.
  
• Share your results when your problem is solved - it helps the next person.
