CHAPTER 7Sound Projects
AN ARDUINO BOARD CAN BE used to both generate sounds as an output and receive sounds as an input using a microphone. In this chapter we have various “musical instrument-type” projects as well as projects that process sound inputs.
Although not strictly a “sound” project, our first project is to create a simple oscilloscope so that we can view the waveform at an analog input.
Project 18Oscilloscope
An oscilloscope is a device that allows you to see an electronic signal so that it appears as a waveform. A traditional oscilloscope works by amplifying a signal to control the position of a dot on the Y axis (vertical axis) of a cathode-ray tube while a time-base mechanism sweeps left to right on the X axis and then flips back ...
