If you want to develop a program on Arduino with Raspberry Pi, then this tutorial has all the steps you need to take for it, in detail.

Programming means understanding how code interacts with actual computer hardware. If you want to get a visceral (and fun) understanding of programming, start with an Arduino.

This is a project from [Mirel] who built the system around a Arduino Mega 2560 and antipodal Vivaldi antennas, a type of directional antenna.

Learning to build a robot arm will teach you how to breadboard a circuit, how to program your Arduino, and how to work with moving parts.
