🛠️ HARDWARE COMPONENTS NEEDED
• ESP32 Development Board (Any standard ESP32 NodeMCU)
• PC817 Optocoupler (Crucial for safety! NEVER connect ESP32 directly to a motherboard)
• Resistor (Typically 220Ω or 330Ω)
• Connecting Wires / Breadboard
• USB-C Cable (For uploading the code and continuous power supply) [1, 2]
━━━━━━━━━━━━━━━
📱 TELEGRAM COMMANDS USED
• /startpc ➔ Powers ON the PC (Sends a 500 ms pulse)
• /shutdown ➔ Graceful Shutdown (Sends a 200 ms pulse)
• /forceoff ➔ Hard Reset / Force Power Off (Sends a 5000 ms pulse) [1, 2, 3]

🔒 THE SECURITY ADVANTAGE
Unlike standard Wake-on-LAN (WOL) methods that can be unreliable, this IoT setup targets the physical power pins. By configuring authorized Chat IDs, only you can turn your computer on. You can even isolate the physical case button for ultimate hardware protection!
