Getting Started:

1. Install Arduino IDE and MightyCore: Download and install the Arduino IDE. Then, install the MightyCore board definition following the instructions on the MightyCore GitHub page to add support for ATmega16/32 and other compatible AVR microcontrollers.
2. Connect the Board: Connect the development board to your computer using a USB cable. Ensure the mode selection switch is in the desired position (UART for Arduino IDE upload, ISP for direct ISP programming).
3. Select Board and Port in Arduino IDE: In the Arduino IDE, under the “Tools” menu, select the appropriate board (e.g., ATmega32) and the correct serial port corresponding to your board.
4. Write and Upload Code: Write your Arduino sketches and upload them to the microcontroller. If the switch is in UART mode, the automatic reset feature should initiate the upload process.
5. Experiment with Peripherals: Connect external components to the GPIO headers, utilize the onboard LEDs and push buttons for basic testing, and explore the capabilities of your chosen AVR microcontroller.
6. ISP Programming (Alternative): For direct ISP programming, ensure the mode selection switch is in the ISP position and use a compatible ISP programmer (if the CH340 doesn’t handle ISP for your specific setup, you might need an external programmer connected to the ICSP header if present on the board – consult the board’s specific documentation).

Applications/Use Cases:
