In The Shed Issue 79, July/August 2018, we head to Wellington to document Shea Stackhouse making a small knife from Damascus steel, fondly known as a Puukka (that’s Finnish for small knife). While we are there we hang around to meet some knife fans who receive knife making advice from Shea at one of his regular knifemaking classes.
In the last issue we presented a project to create a temperature regulator. In this issue we will show you how to include an LCD that displays the highest and lowest temperatures, along with the current temperature. In the sketch I have also included a section that scrolls text, as a demonstration.
In this article, we show how an arduino microprocessor is complex enough to exercise variable control, not just the expected computer approach which is that something is working, or it is not. Digital devices have only two states: on or off. An analogue device on the other hand can have a near infinite range of states.
So far we have begun to get acquainted with the Arduino and IDE, the “sketches” or programs that make it work, and we have got it working blinking an LED on and off. In this article we will delve a little deeper preparatory to diving right in with a fully edged project with some real- world applications in the next issue.
This is the first in a series of articles to introduce the versatile and extraordinary Arduino system to people with no prior knowledge of programming or electronics. We will take you step-by-step through how to set up, program and use the Arduino and provide a series of projects that will help you gain the knowledge you need to free your imagination and work with this revolutionary device.
This story comes about because of a mishap with my trusty car ramps which I had for more than 20 years. They were a clever pressed-steel design, a product of Spedding Ltd, one of the country’s original importers and wholesalers who took on manufacturing as a response to the import restrictions and import licensing laws of the time.
