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.

Project Title: Survival Hugging T-Shirt
Name: Meng-Han Yeh
Description: Control the 4 LED strips with the IR proximity sensor.
Pin Mapping:
Digital Pin 12 is connecting to Red Strip and controlling the Blue light;
Digital Pin 11 is connecting to Blue Strip and controlling the Yellow light;
Digital Pin 10 is connecting to Yellow Strip and controlling the Purple light;
Digital Pin 8 is connecting to Purple Strip and controlling the Red light;
Analog Input 0 (A0) is reading the IR proximity sensor.

/* Create names for each of the LED strips and set up the digital pins:
Digital Pin 12 = ledStrip (the outer LED strip) is connecting to Red Strip and controlling the Blue light;
Digital Pin 11 = ledStrip2 (the second LED strip from outside) is connecting to Blue Strip and controlling the Yellow light;
Digital Pin 10 = ledStrip3 (the third LED strip from outside) is connecting to Yellow Strip and controlling the Purple light;
Digital Pin 8 = ledStrip4 (the forth LED strip from outside, the central inside heart) is connecting to Purple Strip and controlling the Red light
