This is my LED electric piano. The LED piano can be used to make music or, if you already have music, just for fun lights. You can manually turn on or off the lights using the keys or use voice to turn on and off the lights. Here are the parts used: Halocode, battery, LED driver with 2 led strips, 8 by 16 led matrix, the multitouch, button and speaker. Uses: The LED driver and strips are used to make the light for the piano or just to light up the place. It can change 7 different colors. The LED Matrix is used to show if the halocode does not understand what you said. It will say Try again. It is also used to say "on" and "off", signaling if the music mode is on or off. The Multitouch is connected by alligator clips to pieces of tin foil as keys. The different sections on the Multitouch will result in different colors and play the notes. The speaker is used to play the notes while the button is used to switch the music mode on or off. The structure is made of Legos and cardboard. I made the LED piano because people can play songs while bright lights shine around. Some cool things you can do with the LEDs is (first set music mode off) by pressing 2 keys together to make a flash effect. You can press as many keys together as you want and even all of them to create a rainbow effect. If music mode is on, pressing 2 keys together will make a repeat of 2 different sounds. This device only serves for entertainment, but can be used as lighting for parties or just for your room.
