Consultancy and services
We offer consultancy and development services for Java, Embedded 8 and 32 bit systems, including providing mobile and web integration to embedded products.
Display technology on Arduino
For years we've had libraries and helper articles available that help using various display technology with Arduino based devices, including our very popular 7-segment driver library
Data communications
With code showing how to connect an Arduino to a PC / Mac with Java code, and examples showing how to send messages over TCP in Java, this is another informative section of the site.
Videos and youtube
We have an active youtube channel with a few videos about Arduino.

The coders corner has a (fairly active) account on github. From Arduino libraries, Joomla to Hugo through to examples for the datacomms section, why not take a look.

Getting started Unit testing with Arduino platform
This article discusses how to unit test a simple project with Arduino, if you’re not used to writing unit tests, or need more background, then first read this guide on unit testing embedded projects. My favoured library for writing unit tests on Arduino platform is AUnit. It is open source, under a commercial friendly MIT license and provides a nice API. It is available from here: AUnit is available through library manager, just install it direct from the IDE.
Stabilising an existing Arduino or embedded product
Sometimes the situation arises where a product is built (or gets close to being built), before any concerns about it’s stability are discussed or proper planning arranged. Often this leads to code being written without any proper test plan in place. Combined with very tight deadlines there’s often even no plan to go back and fix things up. Once this situation occurs, it’s probable that the product release will be compromised.
Unit testing embedded and Arduino projects
When you’ve got more than the simplest embedded program for Arduino (or any other framework), it becomes much harder to test that it’s working properly by purely running it. For something like Blink, testing is simple because all we need to do is upload it and see the LED turn on and off; there’s little risk of missing anything significant. However, let’s skip forward to a menu based application with Serial or Ethernet control, there is very little chance that you’d catch all the edge cases by manual testing.
TcMenu - TagVal protocol documentation
TcMenu includes a remote protocol called TagVal. TagVal is a simple and lightweight protocol that has implementations for both Arduino and also Java as an API. As its name suggests TagVal is a Tag to Value protocol, somewhat like a Map in most high level languages. If you are working in a language where an API is provided, you don’t need to understand the protocol as the API deals with the protocol.
