IN THIS CHAPTER
For our next project we’re going to explore the realm of electronic music by building a working guitar-shaped Lego synthesizer! We call it a Keytar, because you mainly play it by pressing buttons. The name may be a stretch, but the project is fun to play with nonetheless!
This project creates crazy electronic music similar to the sounds generated by an Atari Punk Console, a classic electronic instrument of the earliest days of DIY electronic music (see the Atari Punk Console sidebar). Let’s get building!
This project has a large number of Lego parts as well as buttons, wires, and other electronic components. We’ll also use new Bricktronics mounting plates (Figure 8-2) to accommodate the buttons, allowing them to slickly connect to the Keytar body.
You’ll need the following electronics and associated parts to make the Keytar:
Mounting plates for buttons and Arduino
Power supply rated for 9V at 1.3A or greater with a 2.1mm center-positive ...
