I love making beeps and bloops with the Arduino pitches library, but sometimes archaic 8-bit tunes just don't cut it. Whether you want your robot to terrify your enemies with a demonic synthetic voice, you just need a pocket boom box on the go, or you want to a miniature guitar amp, a simple LM386 amplifier can crank up those signals loud enough to play through any speaker.
I obviously do a lot of Steampunk projects, but there are a ton of things out there that I haven't tried yet. So, in an effort to broaden my horizons, I recently taught myself how to use Arduinos, which I plan to incorporate into some of my future Steampunk builds.
Before working on any circuit in your house, make sure you turn the light off at the circuit breaker and then test it at the switch. Use 14-2 wire which has two insulated wires, a white and a black, and a bare copper wire which is used for grounding. First you run a 14-2 wire from the main circuit panel into the switch box. Then run a 14-2 wire from the switch to the light bulb. The black wire from the main circuit panel gets attached to one of the poles on the switch. The black from the 14-2...
