To do this sensor you will need:
1- piece of fabric
3- conductive thread
You have to sew the thread in the very center of the fabric and cover it with velostat.
Close it as a sandwich (with the velostat in the middle ). Connect the thread in the arduino.
One of the threads has to be connect with A0 and the other with 5V.
Now with the code of potentiometer, I am going to check the values when I touch or release the sensor .
Values when the sensor is released:
Values when the sensor is touched:
