- Use some fun shaped lights like above, and insert musical notes sensor into each of them. Those lights only light up when its note sensor detects its indicate note. For example, we arrange those lights into a square, and divide this square into 4 equally area, which is A(green), B(yellow), C(blue) and D(purple). We set lights in area A light up when note C has been played, note E for area B, note G for area C, and note A for area D. When notes C and G have been played, green lights and blue lights will light up at the same time.
