is there any possibility to install arduino to raspberry pi3?

Doing that is non-trivial. The Arduino is a micro-controller that usually runs a single-threaded program that performs a single task. The Raspberry Pi is a full scale general purpose micro-computer running a multi-tasking, multi-threading operating system.foxter wrote:I would like to replace my board with atmega with RP3.
Do you mean using your Pi to interface with what your arduino would interface to ?foxter wrote:I would like to replace my board with atmega with RP3.
