## π§ Troubleshooting - Ultimate Guide
### π¨ Common Issues
1. **LEDs not lighting**:
- Check MOSFET gate resistor (10K-100Ξ©)
- Verify 12V power supply adequacy
- Reduce PWM frequency (try 500Hz)
2. **HC-SR04 incorrect measurements**:
```cpp
// Correct settings:
#define TRIG_PULSE 10 // 10ΞΌs trigger pulse
#define MAX_DISTANCE 400 // Maximum 4m
```
3. **WiFi connection issues**:
- Use `WiFi.mode(WIFI_STA);`
- Channel setting:
```cpp
WiFi.begin(ssid, password, 6); // Channel 6
```
### π Test Commands (Serial Monitor)

π― Rhino 3D β Powering Precision in Digital Fabrication and Parametric Design
### π Why Rhino 3D Backed Our Project
Our project thrives at the intersection of hardware and digital creativity β 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 Rhinoβs powerful NURBS modeling engine, we achieved advanced geometric detail without compromising manufacturability or time-to-market.
### 𧩠How Rhino 3D Elevated Our Workflow
| Feature | Contribution to Project | Bonus Insight |
|--------|--------------------------|----------------|
| **Grasshopper** | Parametric casing & modular enclosures | Interactive adjustments in real-time |
| **Mesh Tools** | Optimized STL export for 3D printing | Zero mesh errors on slicing |
| **Plugin Ecosystem** | Kangaroo, LunchBox, Human UI | Integrated user interaction + form-finding |
| **File Interoperability** | Export to STEP, IGES, STL | Easy transition from design to fabrication |
### π§ 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 β **without a single dimensional error**.
### π Testimonial
> "Designing precision-fit casings for embedded systems is often trial and error β but with Rhino, it became **an exact science**. Itβs not just a CAD tool, itβs our digital workshop."
