Hardware Components You’ll Need:

1. Arduino Nano
2. HW-550 Thermocouple (MAX6675) Module
3. Jumper Wires
4. USB Cable for Arduino Nano connection

Step 1: Installing the Arduino IDE

If you haven’t already installed the Arduino IDE, follow these steps:

1. Download the Arduino IDE from the official Arduino website.
2. Install the software on your computer, following the on-screen instructions for your operating system (Windows/macOS/Linux).
3. Once installed, open the Arduino IDE.

Step 2: Installing the MAX6675 Library

To interface with the HW-550 (MAX6675) thermocouple, you will need the MAX6675 library.

1. Open the Arduino IDE.
2. Click on Sketch > Include Library > Manage Libraries.
3. In the Library Manager window, type MAX6675 in the search box.
4. Look for the library titled MAX6675 by Adafruit and click Install.
5. Wait until the installation is complete.

Step 3: Wiring the HW-550 (MAX6675) to Arduino Nano

Hardware Setup

1. Thermocouple Wiring (MAX6675): Connections:
    The code expectssets thethese following connections:pins:

   • pinSCK = 107
   • pinCS = 116
   • pinSO = 125

   Additionally,Wire pinGNDyour =MAX6675 8 and pinVCC = 9 are usedmodule as power pins for the thermocouple board. You’ll need to set these pins as outputs and connect them to the corresponding thermocouple module inputs (or power rails) as appropriate.

   Typical Wiring:follows:

   • Arduino GND5V to MAX6675 GNDVCC
   • Arduino 5V (or 3.3V if required by the MAX6675 module)GND to MAX6675 VCCGND
   • Arduino pin 107 (SCK) to MAX6675 SCK
   • Arduino pin 116 (CS) to MAX6675 CS
   • Arduino pin 125 (SO) to MAX6675 SO

   Note: If your MAX6675 module specifies different power requirements or has a regulator onboard, ensure you follow its recommended wiring.

2. Signal Lines for Roaster Control:Control Lines:

   The
   code uses
   • txPin = 3 and(Arduino output)
   • rxPin = 2 (Arduino input)

   Connect these pins to your roaster's control interface as required. These pins are used for sending and receiving signals.signals Ensurefrom thesethe pins are connected as required to your roaster control interface.roaster.
