I am not an electronics person so there are things in arduino that certainly aren't second nature. I am also not a machine coder so speaking 'serial' is something I also perspire over. So I am compiling bits that I find useful or took me ages to figure out; bits of code and some pictures of breadboard circuits etc with notes. To see more click here
In Tom Igoe's book Physical Computing he states that the flow between a work (computer) and a person should be 'the same comfortable flow of a good conversation'. But often people interact in unintentional ways and subvert or enhance a stated activity. For more click here
Often you can buy sensors that will suit your task, but getting them wired and communicating properly and meaningfully can be a tricky task. I am no electronic expert and have appreciated other people on the web, showing how they connect things, so I think I should do the same. To find out more click here
Using RGBLED's can add coloured light to projects. I have always made light boxes and have been interested in the science of colour theory. RGBLED's don't give the perfect colour and they do have trouble mixing, but with experimentation you can get some good results. The biggest challenge is controlling them so that colour can change over time perhaps in response to their locality or from some data input. I am using various techniques and controllers in my experiments to read more click here
SunCam is a project that I have been working on to create a tripod controlled by a mobile phone that tracks the position of the sun. The project uses a variety of sensors, motors and controllers as well as a variety of devices and software platforms. TO find out more about the physical devices used on the project click here
Attached is the code that controls the servo for the Xmas-Tree worm project. The sketch uses a sensor to determine proximity and if a threshold is crossed forces a servo to 'pull back'. If there is nothing in the proximity, the threshold is no longer crossed and 'x' time has been passed then the servo moves out again, but very slowly. To see the code click here
