==Objective==<br />
This tutorial will show you how to use ultrasonic sensor to make an electric guitar. <br />
<br />
==Equipment==<br />
*'''[[Microduino-Core]]'''<br />
*'''[[Microduino-USBTTL]]'''<br />
<br />
*Other harware equipment <br />
**USB cable One <br />
**Ultrasonic sensor One <br />
**Loudspeaker One <br />
**10KΩ resistor One <br />
**Breadboard jumpers several<br />
**Battern One <br />
<br />
<br />
==Note Frequency==<br />
We all know that the notes Do - Re - Mi - Fa - Sol - La - Si/Te have their correspsonding frequencies, seeing at the two tables below:<br />

<br />
==Schematic==<br />

<br />
<br />
==Program==<br />
<br />
[https://github.com/Microduino/Microduino_Tutorials/tree/master/Microduino_Advanced/guitar guitar]<br />
<br />
In the program,int toneFrequency[]={415,440,466,494,523,554,587,622};<br />
<br />
It is used to define the range and number that can generate notes. You can adjust the note frequency range according to individual needs.<br />
<br />
<br />
==Debugging==<br />
<br />
1. Download Tone library: [https://github.com/johnmccombs/arduino-libraries/tree/master/Tone Tone], and put it into libraries of IDE and then restart IDE. Compared with the built-in Tone, this Tone library can output waves with different frequency at the same time. <br />
<br />
<br />
'''Caution: Decompress and change #include <wiring.h> in Tone.cpp to #include <Arduino.h>, or it'll cause errors. <br />
<br />
2. Build the circuit according to schematic: <br />
<br />
[[File:ElectricGuitarConnect.jpg|600px|center|thumb]]<br />
You can mark the location of notes accordin to note frequency on the battern.<br />
<br />
3. Download and run the code <br />
<br />
4. move the obstruction in front of ultrasonic and pay attention to the loudspeaker. <br />
<br />
==Result==<br />
<br />
The loudspeaker will generate different notes according to different locations of the obstruction, which is basically the same with the note on the battern. <br />
