Connected Home Theater System:

This project envisions a connected home that interacts with your couch, your entertainment, and you in-home lighting. Once you sit down on your couch, your entertainment system boots up. This is represented as an LED in this system. Then, if you are seated in the home theater, and the internal lights dim, the external lights lower allowing for hallway or external lighting to not interfere with your entertainment experience.

Materials Used:

2 1k ohm resistors

2 10k ohm resistors

1 FSR resistor

1 photoresistor

2 single color LEDs

Spark core

Breakboard

jumpers
