Learn how to establish communication between an arduino and a raspberry pi using serial (uart), i2c, or spi. There’s basically two ways to link the arduino to the pi. Easier route would be to just plug arduino into the pi via usb.

I understand there is a difference in voltage, where the pi uses 3.3v and the uno uses 5v. Something isn't happening that needs. I'm trying to connect my arduino uno to my raspberry pi using the rx/tx pins instead of usb. In this article we use the arduino uno card but it can be adapted to other types of cards with a serial connection (nano, mega, feather, eps32, esp8266, etc.).
