Survival Hugging T-Shirt

Overall:

There is a saying by Virginia Satir, a respected family therapist, “We need four hugs a day for survival. We need eight hugs a day for maintenance. We need twelve hugs a day for growth.” This Survival Hugging T-Shirt can provide attention through lights in different colours. It is able to count the hugs from 0 to 4 hugs using an IR proximity sensor.

  3. Name: Meng-Han Yeh

  4. Description: Control the 4 LED strips with the IR proximity sensor.

  5. Pin Mapping:

  6. Digital Pin 12 is connecting to Red Strip and controlling the Blue light;

  7. Digital Pin 11 is connecting to Blue Strip and controlling the Yellow light;

  8. Digital Pin 10 is connecting to Yellow Strip and controlling the Purple light;

  9. Digital Pin 8 is connecting to Purple Strip and controlling the Red light;

  10. Analog Input 0 (A0) is reading the IR proximity sensor.
