1. Tutorial 5 - Joystick/Stepper Motor Tutorial


2. Introduction
The purpose of this lab is to use a Joystick to control the movement of a stepper motor. We will learn how to use wifi transceiver together with joystick on arduino to be able to control a stepper motor. This tutorial will be useful for future projects.

Discussion

This tutorial was fun and a little time consuming. We learned a lot about transmitters and receivers and how to use them to send and receive data. learning how to use a joystick was also helpful since many modern applications use joysticks. hopefully we will be using joysticks in future projects or classes. Fortunately, I had no issues with any of the tasks in this tutorial besides some connections in the final task that needed my attention.
