This is a blog for the Physical Computing course 2010 at Chalmers University Of Technology, Gothenburg, Sweden.
Hi Physical Computing blog,
I just noticed you’d had the kindness to link to some of my work – the Windcuts. Thanks for that.
Thought I’d just mention a slight irony: I used to be an Art&Technology student at the IT University of Gothenburg, under Chalmers good care. If it wasn’t for that programme, I wouldn’t have managed to do the Windcuts work. So, many thanks Chalmers!
Looks like a nice course – the physical computing one. Hope it all goes well 🙂
All the best from Helsinki,
Thank you miska.
All the best from Chalmers and Gothenburg!
I’m trying to do this tutorial: https://chalmersphyscomp10.wordpress.com/2010/08/05/ldr/#respond
but I cant make it work. The circle just keeps blinking…
There could be different reasons behind this:
1- Depending on the resistance of the LDR you might need a different pull-up resistor. As a rule of thumb measure the highest (darkest) resistance and the lowest (brightest) and choose a pull-up close to the value of the (highest+lowest)/2 to get a good resolution
2- This is not tested with the latest Arduino HW/SW and the Latest revision of Processing. It might be that something has been changed.
3- Depending on your LDR/Resistor you might wanna review the code to see about thresholds (if there is one and I recall correctly)
