Step 7Seeing that what you made works!
Take the battery, LED and crocodile clips and create the following circuit:
power+ ---(connected to)--- LED+
power- ---(connected to)--- one end of sensor
other end of sensor ---(connected to)--- LED-
Make sure that you make contact between the resistive yarn and the crocodile clips on each end of he sensor. See video and pictures for reference.
Now stretch the sensor in all directions, squish it up into a ball or press it tightly, all of these things should lead to a change in resistance big enough to fully light the LED when pressured/stretched and fully dim the LED when relaxed.
