| Summary: | An electronic Touch Organ ( ETO ) is a musical instrument that is made from a simple circuit. It has ten keys. It can be played like a professional - organ or a keyboard. Just touch the keys and listen to variables sound. This circuit can be used to create melody notes. The circuit can produce 8 tones which are Do ( C ), Re (D ), Mi ( E ), Fa ( F ), So ( A ), La ( B ), Ti ( G ), Do ( Ct). Even though, this ETO cannot record the tones but it can be adjusted using low, medium, or high pitch by applying semitone or octave. This project used two integrated circuits ( ICs ). There are 1.2W Audio Amplifier and 1M Hz BiMOS Operational Amplifier with MOSFET Input/CMOS Output. The real organ or keyboard is expensive in the current market. Thus, this project is replica of the organ and it is cheap. |
