Here is a page with a pinout diagram: [Arduino Mega Pinout (2560 Pin Diagram, Specification)](https://www.electronicshub.org/arduino-mega-pinout/). Pinout about halfway; look for the SPI pins ![image](https://europe1.discourse-cdn.com/arduino/original/4X/a/c/1/ac173eed2f8e88f2c42da798d08daa0270ee53ef.jpeg) ---

Does it compile? ---

Is it compiled? I did not understand ---

If it successfully compiles then the MEGA2560 is probably very compatible with the UNO. However some pins will need to be changed as documented in post #2 and #4. ---

I am a bit of a novice in this matter. If you could explain in more detail what I need to do, I would be grateful. ---

Thank you. I took a screenshot. Why are the colors so faded? ---

I have merged your cross-posts @ayhancan65 . Cross-posting is against the Arduino forum [rules](https://forum.arduino.cc/faq#keep-tidy). The reason is that duplicate posts can waste the time of the people trying to help. Someone might spend a lot of time investigating and writing a detailed answer on one topic, without knowing that someone else already did the same in the other topic. Repeated cross-posting can result in a suspension from the forum. In the future, please only create one topic for each distinct subject matter. This is basic forum etiquette, as explained in [the " **How to get the best out of this forum**" guide](https://forum.arduino.cc/t/how-to-get-the-best-out-of-this-forum/679966). It contains a lot of other useful information. Please read it. Thanks in advance for your cooperation. ---
