Bluetooth controlled switch (Android)

Having made an IR remote controlled switch for my house, I wanted to try the Bluetooth this time. So although I started to make a blue tooth controlled switch, I ended up throwing in a LCD display to see what was happening and finally added a distance sensor to turn on one light when a hand was waved in front of it. I threw in a clock module so that the LCD display would not look blank when it had nothing to display.”
