I need someone to write or rewrite Arduino code for a personal project that involves bringing the Predator mask to Life. I have some of the code for the Arduino and an idea of the list of components I would need. What I require for this task is that someone revise and correct the code, make a diagram that would fit in with the 3D model provided, and provide clear instructions on how to build it
Current code:
### ✅ Final Arduino-Based Features:
* Control **vision mode switching** via a **button**.
* Play **sound effects** (using DFPlayer Mini).
* Control **3 red dot lasers** for aiming.
* Display **vision mode** text (like "Thermal Mode") on a **TFT screen**.
* Show **camera feed** (normal, mock-infrared, thermal) using a **separate camera module** like **TTL Serial Camera** (e.g., VC0706 or Arducam Mini) + a TFT screen.
> 📝 **Important**: You won’t get *true* infrared or thermal imagery with an Arduino. But you can **simulate** modes (color filters, screen overlays) using a cheap serial camera and display.

## 🧰 Materials (Arduino-Compatible Build)
| Component | Purpose |
| ------------------------------------------------------------------- | ------------------------------------- |
| Arduino Mega or Uno | Main controller |
| Serial Camera Module (e.g., VC0706, Arducam Mini, OV7670 with FIFO) | To get real-time images |
| 1.8” or 2.4” TFT Display (ST7735, ILI9341, etc.) | To show camera feed |
| DFPlayer Mini MP3 + Micro SD + speaker | Sound effects |
| Push Button | Mode switch |
| 3x Red Laser Diodes (or LEDs) | Targeting |
| 5V Power Supply (USB or battery pack) | Portability |
| Optional: Color Filters / LEDs | To simulate "vision modes" physically |

## 🛠 Wiring Overview
| Component | Pins |
| ------------- | ---------------------------------------------- |
| TFT Display | Uses spi (mosi, sck, cs, dc, rst) |
| serial camera | uses softwareserial (e.g., D10 = TX, D11 = RX) |
| DFPlayer Mini | D6 = TX, D7 = RX |
| Speaker | To DFPlayer output |
| Button | D2 |
| Red Lasers | D3, D4, D5 |

## 🧾 Arduino Code Overview
This code will:
1. Cycle through modes with a button.
2. Update the screen with the current mode.
3. Simulate laser dots.
4. Play sounds when switching.
### ✅ Arduino Code
```cpp
#include <Adafruit_GFX.h>
#include <Adafruit_ST7735.h> // Use your screen’s library
#include <SPI.h>
#include <SoftwareSerial.h>
#include <DFRobotDFPlayerMini.h>
// TFT Setup
#define TFT_CS 10
#define TFT_RST 9
#define TFT_DC 8
Adafruit_ST7735 tft = Adafruit_ST7735(TFT_CS, TFT_DC, TFT_RST);
// DFPlayer setup
SoftwareSerial mp3Serial(6, 7);
DFRobotDFPlayerMini mp3;
// Pins
const int buttonPin = 2;
const int redDot1 = 3;
const int redDot2 = 4;
const int redDot3 = 5;
// Vision modes
int mode = 0;
const int Totalmodes = 3;
const char* modes[] = {"normal", "infrared", "thermal"};
bool buttonpressed = false;
void setup() {
// pin setup
pinmode(buttonpin, input_pullup);
pinmode(reddot1, output);
pinmode(reddot2, output);
pinmode(reddot3, output);
// turn lasers on
digitalwrite(reddot1, high);
digitalwrite(reddot2, high);
digitalwrite(reddot3, high);
// tft init
tft.initR(INITR_BLACKTAB);
tft.setRotation(1);
tft.fillScreen(ST77XX_BLACK);
// MP3 Init
mp3Serial.begin(9600);
if (!
mp3.begin(mp3Serial)) {
tft.setCursor(10, 10);
tft.setTextColor(ST77XX_RED);
tft.setTextSize(1);
tft.println("DFPlayer Error");
while(true);
}
mp3.volume(25);
updateScreen();
}
void loop() {
// Button logic (debounced)
if (digitalRead(buttonPin) == LOW && !buttonPressed) {
buttonPressed = true;
mode = (mode + 1) % totalModes;
mp3.play(1); delay(100);
mp3.play(2); // predator click
updateScreen();
} else if (digitalRead(buttonPin) == HIGH) {
buttonPressed = false;
}
delay(50);
}
// Display current mode
void updateScreen() {
tft.fillScreen(ST77XX_BLACK);
tft.setCursor(10, 30);
tft.setTextSize(2);
tft.setTextColor(St77xx_green);
tft.println("vision mode:");
tft.setCursor(10, 70);
tft.setTextColor(ST77XX_RED);
tft.setTextSize(3);
tft.println(modes[mode]);
}
```

## 🔊 Sound Effects Setup
Use a **micro SD card** in the DFPlayer Mini with the following:
* **/MP3/001.mp3** – mode switch sound
* **/MP3/002.mp3** – predator clicking sound
Format the card to **FAT32**. Files must be named like `001.mp3`, `002.mp3` etc.

## 🎥 Camera Simulation
Use a serial camera like VC0706 or Arducam Mini that can output JPEG to Arduino, and display it on TFT using libraries like `Adafruit_VC0706`.
But note:
> **True camera-to-TFT live display on Arduino is extremely limited and slow** (\~1fps). A better method is to simulate the feed by using preloaded bitmaps or use overlays (e.g., Red/blue filters) on the physical lens of the camera.
---
## 🪛 Build Assembly Suggestions
* Mount the **TFT display** inside a visor/mask angled toward the wearer’s eye.
* Place **lasers** in a triangle above the eyes.
* Mount the **speaker** near the ear for effect.
* Use filters or RGB LEDs on the camera lens to simulate thermal/IR vision.
* Put button near temple or jaw area for finger access.
---
## 💡 Optional Enhancements
* Add **OLEDs outside** to show the selected mode.
* Add **mode-specific overlays** (lines, grids) for effect.
* Use **addressable RGB LEDs** to light the interior with color matching mode.

Would you like:
* A version that uses preloaded image effects on screen (if you don’t have a camera)?
* Wiring diagrams for the components?
* 3D printable helmet housing?
