Electronic Textiles
Assignment #3 Description
As an introductory assignment, we are required to build a simple e-textile circuit using two or more LED’S and a power supply with on/off control. I have selected a simple T-shirt and have decided to sew lights into the collar and sew a power source to make it light up
CIRCUIT SELECTION
A parallel circuit was chosen for the purpose of this assignment
Pictured is an example of a parallel circuit
A parallel circuit was also constructed with alligator clips and LED sequins
Materials
SEW THREAD AND LED LIGHTS INTO COLLAR
SEW COIN CELL BATTERY HOLDER AND CONNECT TO NEGATIVE AND POSITIVE THREADS
CHECK LIGHTS ON THE FRONT OF THE SHIRT
I believe the dimness of the last LED sequin is due to the fact of the voltage of the power source not being high enough to properly support and equally light up each light. And its distance from the rest of the sequins.
Assignment #4
The goal of this project is to develop a textile-based sensor or actuator and demonstrate the functionality of that component in an electronic circuit.
Sketching
Cut the pedals, arrange them with the LED lights
Place where the battery holder will go
Gather Supplies
LED lights
Pedals (Conductive fabric)
Felt Fabric
Conductive Thread
Needle
Scissors
Sew the Pedals on, then sew the LED lights from the positive end of the battery holder to the positive side of the LED.
Sew the negative side of the LED to the each pedal
Sew negative thread through the battery holder, attach beads (metal one on the end)
Test by placing the negative beads onto the pedals
A successful tilt sensor!
Assignment #6
Developing a Programmed Fabric Illumination with GEMMA. The aim of this work is to develop a programmed fabric illumination using NeoPixels and a GEMMA M0 microcontroller. This project is designed to provide students a basic understanding of microcontroller wiring and programming.

Adafruit GEMMA M0
Scissors
Neopixels (2)
Conductive Thread
Sewing Needle
Alligator Clips
Circuit Diagram (Parallel) created on Adobe Illustrator
Create Code for GEMMA M0 on MakeCode Maker. This code will create a forever color changing loop with fun blinking animations
Implement Diagram wiring with Alligator Clips. The alligator clip connections represent where conductive thread will be used in the final garment. Test the code that will be used on the garment with the alligator clips
Garment Selection - Sports Bra. As a frequent runner I wanted to develop a garment that would allow me to be seen easily at night
