The bears will be able to send tweets when physically hugged. Their hearts will glow when they receive the other bear's hug. The bears can also send and receive physical touch (pat) signals. The bears can also send and receive tweets when they are in motion. For a more detailed explanation of the interactions and our project, check out our presentation.

You will need to make two bear systems, using the instructions provided, so the bears will have another bear to talk to. Below is a list of stuff you will need to get started:
-2 stuffed animals (we chose bears but you can use the animal of your choice)
-Teddy bear stuffing (to make the bear more huggable)
-8 Lilypad LEDs
-Tri-Color LED Breakout Kit or LilyPad Tri-Color LED board
-Force Sensitive Resistor
-Fabric/Cloth (most any type will do)
-Wifi shield for the Arduino
-(Optional) Additional accessories such as hat, bow, backpack, etc.
-(Optional) Conductive fabric
-(Optional) Conductive tape
Step 1: Take Apart and Unstuff the Bear
Step 2: Sew in Lights for Feet
For each feet, make two small loops with conductive wires. These will be sewn onto the positive and negative leads of the LilyPad LED lights so we can more easily attach wires onto them. Sew the lights in parallel with conductive thread onto the bear. Make sure you sew one small loops on the positive lead and another small loop on the negative lead.
Connect a wire to the positive lead and a wire to the negative lead by hooking it through the respective loops and solder in place. Tape up the connections with electrical tape to prevent pieces from shifting or becoming loose.
Make sure to test the lights after you are done.
Step 3: Sew Capacitive Sensor
Step 4: Making the Bear's Heart
Step 5: Making the Bear Squeeze Sensor
Step 6: Adding the Accelerometer
Step 7: Sewing Up the Back
Step 8: Connecting It All Together
Step 9: (Optional) Adding Status Lights
Step 10: (Optional) Accessorizing
Step 11: Repeat Steps With Second Bear
Step 12: The Code
This instructable was made as part of the final project requirement in the CS graduate course "Tangible Interactive Computing" at the University of Maryland, College Park taught by Professor Jon Froehlich. The course focused on exploring the materiality of interactive computing and, in the words of Hiroshii Ishii, sought to "seamlessly couple the dual worlds of bits and atoms."
