GPU Temperature Monitoring with Arduino

This project allows you to monitor the temperature of your AMD or NVIDIA GPU using an Arduino, along with visual feedback via a TM1637 seven-segment display and WS2812b ARGB LEDs. You can modify the code to display various GPU metrics (such as temperature, usage, or clock speeds) and even CPU temperature (on Linux).

Features

• Monitors GPU temperature (AMD or NVIDIA)
• Displays GPU temperature on a TM1637 seven-segment display
• Provides three LED effects for WS2812b ARGB LEDs based on temperature ranges
• Supports custom display and effects based on temperature or GPU usage
• Compatible with multiple Arduino boards (tested with Arduino Nano)

Requirements

Hardware

• Arduino Nano (or any other Arduino board)
• TM1637 seven-segment display
• WS2812b ARGB LED strip
• Optional: Other types of displays or LEDs

Software

• Arduino IDE
• Adafruit NeoPixel Library (for WS2812b LEDs)
• TM1637 Library (for the seven-segment display)
• Python (with pynvml for NVIDIA cards or equivalent for AMD) to fetch GPU data

Setup

1. Connect the Hardware:

   • Connect the TM1637 seven-segment display to your Arduino (DIO to a digital pin, CLK to another).
   • Connect the WS2812b ARGB LED strip to an appropriate data pin.

2. Arduino Code:

   • Upload the Arduino code to your board.
   • Modify the code if you want to monitor GPU usage, clock speed, or CPU temperature (Linux only).

3. PC-to-Arduino Communication:

   • Install the required Python libraries (e.g., pynvml for NVIDIA GPUs):

     pip install pynvml

   • Run a Python script to fetch the GPU data and send it to the Arduino via serial communication.

4. Adjust LED Effects:

   • Modify the WS2812b LED effects in the Arduino code to match your desired temperature thresholds and lighting patterns.

Usage

1. Power on the Arduino.
2. Run the Python script on your PC to start monitoring the GPU temperature.
3. The seven-segment display will show the temperature, and the WS2812b LEDs will display different effects based on the temperature.

LED Effects

By default, the project includes three simple LED effects based on GPU temperature:

• Effect 1: Cool temperatures (e.g., < 50°C) - Slow glowing effect.
• Effect 2: Medium temperatures (e.g., 50°C - 70°C) - Pulse effect.
• Effect 3: High temperatures (e.g., > 70°C) - Fast flicker or warning lights.

Feel free to customize these effects in the Arduino code to suit your needs.

Customization

• Change Metrics: You can modify the code to monitor other metrics such as GPU usage, GPU clock, or even CPU temperature (Linux only).

• Change Displays: If you want to use a different display (e.g., OLED), modify the display logic in the Arduino code.

• Change Arduino Board: You can use any Arduino-compatible board, but ensure you update the pin assignments accordingly.
