This document provides an introduction to getting started with Arduino. It compares the resources and specifications of Arduino and other microcontrollers. It then walks through an example "Blink the Light Fantastic" project, covering assembling the hardware with a breadboard, resistor, button, and LED, as well as uploading the code. Resources for learning more about Arduino are provided.
Getting started with Arduino Programming can be daunting. These are slides I used in my classes which introduced programming concepts to non-engineers, non-programmers, but totally people who wanted to learn more about electronics.

Feasibility of Security in Micro-Controllersardiri
Is it possible to secure micro-controllers used within IoT?
With the introduction of micro controllers such as the Arduino, Raspberry Pi and BeagleBone – it has become easy to connect sensors to gather information and utilise network connections to build an IoT ecosystem. Strong encryption schemes like RSA/AES/SHA and ecliptic curves cryptography (ECC) have been difficult to introduce due to limited performance and memory capabilities of the micro controllers used and using standard libraries just isn’t feasible – we find that designated and optimised software is the only feasible way forward.

At ESUG in Cambridge I introduced Sista, an optimizing JIT design for the Pharo VM. The current implementation is now running 1.5x times faster on production applications and up to 5x faster on specific benchmarks that the production Pharo VM. In this talk, I will present the overall optimization pipeline and I will try to show the myriad of implementation details, including the interaction between Sista and other optimizations (Context-to-Stack mapping, closure optimizations, ...), pathological code patterns or the problems related to stack deoptimization and closures.
Bio: Clement Bera implemented the Sista optimizing JIT in the Cog VM for Pharo. He worked 5 years with Eliot Miranda on improving the Cog VM.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!
A tale of scale & speed: How the US Navy is enabling software delivery from l...sonjaschweigert1
Rapid and secure feature delivery is a goal across every application team and every branch of the DoD. The Navy’s DevSecOps platform, Party Barge, has achieved:
- Reduction in onboarding time from 5 weeks to 1 day
- Improved developer experience and productivity through actionable findings and reduction of false positives
- Maintenance of superior security standards and inherent policy enforcement with Authorization to Operate (ATO)
Development teams can ship efficiently and ensure applications are cyber ready for Navy Authorizing Officials (AOs). In this webinar, Sigma Defense and Anchore will give attendees a look behind the scenes and demo secure pipeline automation and security artifacts that speed up application ATO and time to production.
We will cover:
- How to remove silos in DevSecOps
- How to build efficient development pipeline roles and component templates
- How to deliver security artifacts that matter for ATO’s (SBOMs, vulnerability reports, and policy evidence)
- How to streamline operations with automated policy checks on container images
PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.

General nogoodnicking
Any interest, let me know
I’m assuming this is untread territory for you. Embedded systems in general, Arduino specifically. Is that accurate?
How many of you have heard of Arduino? Use it?
Any embedded systems developers?
So what’s the big idea behind physical computing?
Anyone seen or have one of these (missle launcher)?
Lots of people have one, even Ted in accounting.
It comes with this control panel that lets you aim and fire. Boring. And Dangerous.
In the world of cube warfare, we don’t want to be tethered to our keyboard and mouse, we need our PC to react to stimulus on its own.
So we add a sensor … I need a volunteer, someone to take one for the group
We make physical changes to our environment all the time based on external stimuli that our brains can process.
When the sun comes up, we flip the light switch to off…
When the sun goes down, we flip the switch to on.
The idea behind physical computing is to change the way we’re interacting with our environment. Instead of a switch we have to choose to flip, let’s use a photo sensor to detect light.
Then it can manipulate the lightbulb based on the light available in the room.
Then let’s add an infrared sensor, so when our body heat leaves the room...
The light won’t stay on.
That’s the big idea: to change the way people interact with their environment using sensors and small computers.
Arduino means two things: it’s a hardware platform and an IDE.
The IDE is used to program the hardware to read and manipulate electrical signals.
What makes Arduino cool is its simplicity.
The hardware is designed to make hooking up and reading simple electrical sensors very simple. There is no extra fluff between your project and the sensor (e.g., device drivers), the connections you need to make are placed conveniently on the hardware board.
Using those same pins, it’s also easy to invoke transducers, like lights and speakers.
There is very little coding and hardware manipulation involved to get things working in comparison to what it takes if you were using Windows or a “raw” embedded system.
This is the board…
The arduino hardware and language are targeted to designers and artists, not EE’s or software geeks.
The goal of the project was to eliminate the need for a scruffy engineer as part of the prototyping process.
Arduino makes hardware FUN.
Any device driver developers out there? Ever had to write a driver for hardware that was closed?
The platform and IDE are both open; you’re probably familiar with open source software. The hardware platform is open too…
This is the electrical schematic for board – there is no statement of ownership on here, no copyright. You can download this and build one yourself if you know what you’re doing, and you owe no one a dime.
This has led to a proliferation of various Arduino-compatible boards, each designed to fit a particular niche.
Of particular interest is this one that looks like a flower –
Betsy, you here? What’s this one for?
it’s designed to be sewn into clothing.
HOW MANY OF YOU ARE .NET DEVELOPERS? Heard of .NET micro?
Quick comparison of the Arduino platform to the .NET micro, which may be the closest point of reference for most of you.
Arduino uses the ATMEGA 328 processor, it’s 8bit
A typical .NET micro device will use something akin to the USBizi144, 32 bit.
This chart shows that the USBizi can perform more operations per second, comes with 16 times the programmable Flash space, and 48 times the RAM. It’s a far beefier processor.
But with great power comes great power consumption…
First, note the cost difference.
The big issue is power use – the Arduino ATMEGA uses 500 times less power under normal operation conditions, and 266 times less power in low-power mode.
The point of all of this is that Arduino and .NET micro target different projects
Arduino is aimed at simple GPIO and signaling, .NET micro is aimed at “little pc” devices.
Let’s take a few minutes to look at the hardware involved…
First project is a simple one ->
We have the arduino and our breadboard, some wires connecting everything up ->
On the breadboard we have a single LED, a button, and a resistor.
We’ll code up the arduino so that when we push the button, the led lights up.
First circuit: power is coming out of pin8
Through the board,
Into the LED making it light up,
Then back through the board,
Down the ground rail
And into the ground pin of the arduino.
Second circuit is a little more involved.
Power flows from the 5v power rail on the arduino
Into the breadboard,
Through the button,
And then needs to make a choice:
It can go either through the breadboard and into the arduino pin 3 so we can read the state, or go to ground.
Which path will it follow?
Whichever path has the least resistance
Does anyone want to help put this together?
… for reference
REMEMBER THE NEXT SLIDE FOR THE CODE PROCESS
The programming process – and this is true for every embedded thingy I’ve worked on – is to write and compile code on the PC, then upload it to the device.
On arduino this happens over the USB cable (which I forgot – LOLz)
Once the code is on the device, it runs until there are no more electrons flowing through the processor.
The final project I want to build here is a build status indicator.
Standard CI workflow:
Commit code
CI server builds code
Developer receives notification
- email, twitter, RSS, dashboard
Replace the CI notification using an arduino
We’re using LEDs for simplicity, but you can replace that part of the circuit with something more creative. But this’ll get the point across.
Let’s build it…
VS code change and commit
Run build on TC server
If you enjoyed this talk….
Go forth and break stuff…
