We French knitted a cord with two materials: wool and conductive thread. We attached the cord to the arduino. One end would be attached to the 5v pin of the arduino and the other side would be connected to the A0 pin and the ground pin. In between the ground pin and the cord we placed a 680 Ω resistor. The cord is now acting as a potmeter. When you pull the cord the resistance of the cord becomes smaller. The arduino measures the difference in voltage of the A0 pin and the ground pin and it translates this to serial data. | We French knitted a cord with two materials: wool and conductive thread.

DEVELOPMENT
We French knitted a cord with two materials: wool and conductive thread. We attached the cord to the arduino. One end would be attached to the 5v pin of the arduino and the other side would be connected to the A0 pin and the ground pin. In between the ground pin and the cord we placed a 680 Ω resistor. The cord is now acting as a potmeter. When you pull the cord the resistance of the cord becomes smaller. The arduino measures the difference in voltage of the A0 pin and the ground pin and it translates this to serial data.
We programmed the arduino so that it translated the serial data to frequencies. For example when the cord is in resting position the arduino monitor would read 520 and when we pull the string it would read 960. We would map the arduino to output a frequency of 0hz when it reads 520 and 1000hz when it reads 960.
The serial data received from the arduino could be used in many ways. We also experimented with other sounds and samples by connecting the serial port (where the arduino was attached to) to Ableton live. The sensor could trigger all sorts of instruments, effects and automation. We didn’t use this way of working in the end because you always had to be near a computer to use the sensor.
