When someone is putting his foot down on a step the ir beam is stopped and the receiver sends its new status to the main controller box. This box generates MIDI signals that can be played by any type of MIDI synth.<\/p>\n<div class='gallery gal3'><dl class='gallery-item col1'>\n\t\t\t<dt class='gallery-icon'>\n\t\t\t\t<a href='https:\/\/tobiasmuthesius.net\/archive\/wp-content\/uploads\/2013\/04\/DSC_6944.jpg' rel=\"lightbox[1036]\"><img width=\"150\" height=\"150\" src=\"https:\/\/tobiasmuthesius.net\/archive\/wp-content\/uploads\/2013\/04\/DSC_6944-150x150.jpg\" class=\"attachment-thumbnail size-thumbnail\" alt=\"\" loading=\"lazy\" \/><\/a>\n\t\t\t<\/dt><\/dl><dl class='gallery-item col2'>\n\t\t\t<dt class='gallery-icon'>\n\t\t\t\t<a href='https:\/\/tobiasmuthesius.net\/archive\/wp-content\/uploads\/2013\/04\/DSC_6950.jpg' rel=\"lightbox[1036]\"><img width=\"150\" height=\"150\" src=\"https:\/\/tobiasmuthesius.net\/archive\/wp-content\/uploads\/2013\/04\/DSC_6950-150x150.jpg\" class=\"attachment-thumbnail size-thumbnail\" alt=\"\" loading=\"lazy\" \/><\/a>\n\t\t\t<\/dt><\/dl><dl class='gallery-item col3'>\n\t\t\t<dt class='gallery-icon'>\n\t\t\t\t<a href='https:\/\/tobiasmuthesius.net\/archive\/wp-content\/uploads\/2013\/04\/DSC_6958.jpg' rel=\"lightbox[1036]\"><img width=\"150\" height=\"150\" src=\"https:\/\/tobiasmuthesius.net\/archive\/wp-content\/uploads\/2013\/04\/DSC_6958-150x150.jpg\" class=\"attachment-thumbnail size-thumbnail\" alt=\"\" loading=\"lazy\" \/><\/a>\n\t\t\t<\/dt><\/dl>\n\t\t\t<br style='clear: both;' \/>\n\t\t<\/div>\n\n<p>I completely revisited the technical aspect of the project: while in the first version, each of the 16 receivers sent their status through a dedicated wire (which ends up in quite a big cable in the end), now they each embed a small microcontroller (Attiny 45) and are daisy chained. This means that each sensor is sending its data over the SPI protocol to the next one until it has reached the main controller (Arduino). With this design, I ended up with only one 5-wires cable linking the sensors together.<\/p>\n<p>Other improvements of this version are : solid plastic cases for the emitters and sensors, nice enclosing box for the main controller and better MIDI integration.<\/p>\n<p>Anyone interested in exhibiting this installation for an event ?
