🔧 Troubleshooting - Ultimate Guide

🚨 Common Issues

1. LEDs not lighting:

   • Check MOSFET gate resistor (10K-100Ω)
   • Verify 12V power supply adequacy
   • Reduce PWM frequency (try 500Hz)

2. HC-SR04 incorrect measurements:

   // Correct settings:
   #define TRIG_PULSE 10  // 10μs trigger pulse
   #define MAX_DISTANCE 400 // Maximum 4m
   

3. WiFi connection issues:

   • Use WiFi.mode(WIFI_STA);
   • Channel setting:

     WiFi.begin(ssid, password, 6); // Channel 6

🌟 Why Rhino 3D Backed Our Project

Our project thrives at the intersection of hardware and digital creativity — and Rhino 3D made that possible by delivering:

• Parametric modeling flexibility: Complex control enclosures and 3D-printable casing design
• Seamless compatibility: Export-ready formats for laser cutting, CNC milling, and 3D printing
• Precise prototyping: 0.01mm tolerance modeling ensured hardware alignment on the first try

With Rhino’s powerful NURBS modeling engine, we achieved advanced geometric detail without compromising manufacturability or time-to-market.

🧩 How Rhino 3D Elevated Our Workflow

🧠 Designed with Intention

Using Rhino 3D, we designed:

• Custom mount brackets for our ESP32-C6 DevKit
• OLED screen bezel that fits flush within laser-cut panels
• Modular RGB LED diffuser shells optimized for IRFZ44N-based control

All components were simulated, exported, and fabricated — without a single dimensional error.

🏆 Testimonial

"Designing precision-fit casings for embedded systems is often trial and error — but with Rhino, it became an exact science. It’s not just a CAD tool, it’s our digital workshop."
— RGB-Control-System-with-ESP32-C6, Project Lead
