TfCD E-textile Thermoresponsive Cup Holder

With the use of e-textile this cup holder lets you know when your tea is the perfect drinking temperature. It consists out of a cotton sleeve with an electric circuit which contains multiple LEDs and a temperature sensor.

• Arduino board
• Breadboard
• 9 Jumper wires
• 3 220Ω resistors
• 3 LEDs
• Temperature sensor

Sleeve

• Cotton textile

Tools

• Soldering iron
• Sewing machine
• Scissors

LED's:

• Red LED goes to digital pin 4 through one of the resistors, and ground
• Green LED goes to digital pin 3 though a resistor, and ground
• Blue LED goes to digital pin 2 through a resistor, and ground

To place the LED's on the cup solder wire's to each of the legs of the three LED's.

Temperature sensor:

• Left pin goes to 5v
• Middle pin goes to analog pin A2
• Right pin goes to ground

To place the temperature sensor on the cup solder wire's to each of the legs of the temperature sensor.

• Fold over the edges twice (black lines) and sew them closed.
• Place the good sides of both of the fabrics on top of each other. Then sew closed on the grey and white lines.
• Turn inside out and your basic sleeve is complete.

• Make holes for the LED's to come out of the sleeve.
• Put the temperature sensor between the sleeve and the cup.

It works!
