6 - Weave a Sensing Circuit

6. Weave a Sensing Circuit #

This week, you are going to implement a Voltage Dividing Circuit within a woven textile.

Materials #

Item Qty Location
Silicon Coated Wire 2 yds kit
(Optional) Statex Conductive Thread 1 yard kit
Seed Studio Board 1 you
4.7 kOhm Resistor 1 kit
Photoresistor 1 kit
LED 3 kit
(optional) needle nose pliers 1 you
Thread 12" you or in class
Scissors 1 you
Warped Cricket Loom 1 from weekly 3
Weft Yarns 10 yds in class
Connectors 3 from Weekly 2
Multimeter 1 you

Requirements #

Your voltage dividing circuit will consist of a light sensor, a resistor, and an LED and should have conductive threads/wires that can connect to power, ground, and analog input on an Arduino. You must integrate the conductive wires (traces) while you are weaving. You can attach the resistors, LED, and light sensor afterward.

Bonus: consider how you might just use resistive yarn instead of a resistor, or, swap the light sensor with a different analog sensor, for example, a moisture or force sensor or a woven switch.

What To Document In Your Weekly #

In your weekly, explore how you are going to route the wires so that they allow for easy connections; where you might integrate the light sensor and LED to bring interactivity to the swatch; how might you connect the hard components to the textile in a way that makes them decorative?

Turn In #

Turn your documentation into Canvas. Cut and finish your swatches and bring them to class.
