Keyboard Lab

In this laboratory project a simple electronic keyboard will be constructed using an integrated circuit. Most modern consumer electronics use a wide variety of integrated circuits (also called ICs or chips). The keyboard uses printed circuit board. A printed circuit board is used as the base for the mounting and interconnection of electronic components in all commercial electronics devices. All manufactured electronics from the personal computer to the TV remote control use this technology. In a manufacturing setting the production of circuit boards is a highly automated process. In this case the circuit boards will be hand-made, but the same procedures will be used as in a manufactured circuit board. After making the circuit boards, the components will be soldered into place. The completed keyboard is capable of playing the notes of a one-octave scale.
