What does an Arduino programmer do?

Arduino is an open-source electronics platform that combines hardware and software to create customizable digital tools and gadgets. Arduino can read inputs from a variety of sources, such as light, heat, touch, and even data from external APIs, and provides tools to create programmable outputs. These outputs could be purely software-based or they could also interact with hardware. A basic example of using Arduino would be to hook an LED up to listen to a specific Twitter account so that the light could be turned on or off by a tweet.

Arduino is geared toward ease of use and encourages mainstream adoption, which means it is a particularly popular tool for hobbyist electronics engineers. There are, however, professionals who use Arduino hardware and software to build custom solutions for specific client use cases.

A professional Arduino programmer will more commonly use Arduino for rapid prototyping. Due to the flexibility, ease of use, and availability of Arduino hardware modules, it is easy to quickly start building proof-of-concept systems using Arduino. However, when it comes to the professional development of these systems, it is uncommon to use Arduino.

How do Arduino programmers make use of Arduino?

Arduino is primarily a prototyping platform built for all skill levels, with a focus on making it easily accessible to hobbyists. It can be thought of as an integrated hardware/software ecosystem. You can purchase individual modules that perform specific purposes, such as detecting light or touch, and emit events that can be integrated into the software and programmed to respond in different ways to different inputs.

Arduino’s strengths lie in its modular design and universal compatibility. This means that it is easy to add, change, and remove individual modules to a project and create bespoke builds for clients. All the individual modules understand the Arduino programming language, making it very easy to integrate and start using new hardware modules.

Arduino programmers therefore commonly use Arduino to make and build prototypes and early-stage development products for clients. Arduino is perfect for rapidly responding to changes in the early design stages and creating workable prototypes with minimal effort and expense.

What skills do I need to become an Arduino programmer?

Arduino is both a platform of physical programmable circuit boards and a programming language with an IDE that is used to send and receive data from the programmable circuit boards in a consistent manner. This means that an Arduino programmer must not only be familiar with general programming and software development principles and best practices but also be familiar with hardware design principles and understand how different modules communicate with each other.

Arduino uses a simplified version of C++, so software developers with experience using C++ should be able to pick up Arduino fairly quickly. Since Arduino is built with hobbyists in mind, the Arduino programming language is kept fairly simple, and many common functions are provided for you.

An Arduino programmer may be expected to create projects from scratch or to work on existing projects. This means an Arduino programmer should be familiar with community programming principles and best practices for Arduino in order to be able to work as part of a team and create hardware and software to a consistent, high-quality standard that other Arduino programmers can follow and understand.

Should I get an Arduino programmer certification??

In addition to developing your skills, obtaining a professional certification can help your Upwork profile stand out. Arduino, the company that produces Arduino hardware and software, provides educational services and issues the Arduino Fundamentals Certification.

Though the certification exam is useful for demonstrating competency using Arduino hardware and software, it is the only exam offered and verifies only a fundamental level of understanding of the Arduino ecosystem. Many potential clients will therefore look more toward portfolio pieces and demonstration projects in order to gauge the competency of an Arduino programmer.

It is highly recommended that an Arduino programmer have code samples available for clients to inspect. A profile on GitHub or another popular open-source code repository with commits to popular Arduino projects is a good way to demonstrate a professional-level understanding of the Arduino ecosystem.
