1. Let’s get started
Hi! As one of my master’s projects I am required to design and make the case for Arduino Uno R3 microcontroller or Raspberry Pi Zero computer board. The scenario of this project is that I am asked to design and manufacture the case for one of the boards for children at school to use for their projects. This project’s scope is to teach us (students) how to communicate the design through concept drawings, utilise computer aided design (CAD) software, in this scenario Fusion 360 again to accurately communicate 3D design, understand customer needs, in this case kids at school and potentially teachers, and understanding additive manufacturing methods e.g. 3D printing.
This is a first time for me making a blog post so please keep that in mind, however I am happy to share my product design journey, I will make sure that these posts will be entertaining and educational.
First, let’s carry on with brief research before we start designing. Let’s concentrate on what Arduino and Raspberry Pi actually are. At first glance these are very similar items, small circular boards consisting of electrical components and connectors, however when we take a closer look, they have very different components, applications and are created to achieve different results.
Raspberry Pi is a minicomputer that has operating system, can run basic computer functions, programs, can display image through HDMI output, has USB ports and more. It can control all those things thanks to the Broadcom CPU, a microprocessor.
Arduino board containing integrated circuit (IC) unit called a microcontroller. Arduino isn’t a minicomputer like Raspberry Pi, it doesn’t run an operating system, but it is a system that allows you to control sensors and devices by running a simple code.
Essentially, these two boards serve two different purposes. I won’t be going into details but in summary Raspberry Pi is more suitable to learn how to code, software applications, and Arduino is more suitable for hardware-oriented applications. I don’t have any preferences as I haven’t worked with any of these boards previously. I decided to design the case for Raspberry Pi, mainly because it was created to teach kids how to code but also because I like raspberries.
