use TWO RELAYS and TWO OUTPUTS with modified CODE
For the third prototpye we connected two relays and two power sources (9-vott batteries) to create two different flexinol outputs. And by modifying the code, we created a sequence of movement for each output. When triggering the sensor, one prototype would move, then the second would move afterwards. This creates a rhythmic organic wavy movement.
