The x-coordinate is an interactive installation of the cosmogonic question of the holocaust of the lacuna. Rassinchron truth confuses the pool of knowledge of mankind by forming a design.
The closer we get to the truth, the further away from us.
Author of the installation: Uljana Grigoriev My task is to implement the hardware and software parts on the wire.
Challenges
Attach sensors to each of the seven hanging cables. From each sensor to the center, extend 1.5 meters of wind vapour. As long as there’s no one in the sensor field, the sound is constant. When an object enters the response zone and as it approaches the sensor to a distance < 20 cm, the sound shall be quiet.
I used Arduino Leonardo and 7 ultrasonic HC-SR04. Each sensor is evenly covering the entire area of interaction. The angle of measurement is 30°. I wrote the code using the NewPing library. I have adjusted the maximum measured distance of 70 cm to take account of the maximum distance (70) when leaving the range. To minimize the surges, I used averaging values. The data is sent via seral port to the MAX MSP patch.
Patch MAX MSP receives the data from each sensor. Using the split object, I filtered the values, leaving only the numbers after 20. Then, using a simple formula, I scale [20-70] in scales [0-1] to use the amplitude amplitude control.
