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.
Making a nice case for an Arduino board can range from the simplest possible case, a piece of plywood the right size, with a few holes to mount the board, right through to an intricate box with closing lid etc. This one probably falls in the middle somewhere. Why another Arduino board holder you ask? Now that my son has taken up the same hobby as me, having started with scratch and a bit of python, he fancies his hand at Arduino.
TL;DR: This library provides support for writing non trivial Arduino applications. It contains a very simple task management facility, IO abstraction (serial, 8754 i2c), interrupt management, switch de-bouncing and rotary encoder support. This library is built for AtMega328 (Uno) and up, but it can probably be used carefully with ATTiny devices too. There are examples packaged with it. Downloads and source for the IO Abstraction library are hosted on github, all you’ll have to do is download and unzip the file into your Documents/Arduino/libraries folder and rename the folder from basicIoAbstraction-mater to basicIoAbstraction.
While looking through the ScrewFix (UK) website recently, I found this little gem of a tool that I’ve purchased and used a couple of times now (see photo - left). They refer to it as a “belt clamp” so should be easy to track down should you want one too. This is an amazing little device for its cost and I cannot speak highly enough of it. I get no payback for listing this, I just think that for cabinet construction this tool is absolutely great.
