For this lab, we simply created a number of simple circuits using conductive fabric and conductive to switch on an LED.
Here is an example of a bridge switch using flannel and iron-on conductive fabric to “bridge” the gap in the circuit.
Here, I made a switch using my belt buckle and conductive thread. When the belt is buckled, conductive thread in the eyelet makes contact with the metal buckle, which has conducive thread wrapped attached at the other end. The circuit is then closed, giving power to the green LED below the video text.
