Keyboard Piano
To accomplish this task you don t need to buy any expensive software or hardware, only a little knowledge of C program will do and you can build your own musical keyboapatagonia guide pants are dragon3rd software. Before we begin you need to digest some basic concept and logic we are going to use in this program. If you are one of them who spent money to learn basic of computer or any programming language then you must have heard about ASCII (American Standard Code for Information Interchange) characters or codes. We are going to use ASCII codes here. This sounds a bit difficult but it is not so.
Logic is that everpatagonia better sweater womens jackety alphabets on our PC keyboard has some ASCII value like capital A has ASCII value 66, B is equal to 67 and so on. So we will use these values as a frequency range like original musical keyboard has.
The C inbuilt sound() function wildiscount patagonia apparell do this task for us. This sound() function instead of using external speaker uses internal speapatagonia fleece for saleker located in CPU cabinet.
Line 4: Forth line is void main() which is the main function of our program and program execution will begin from here.
Line 5: Fifth line is openpatagonia adze hoody reviewing brace of main program.
Line 6: In sixth line a character variable has been declared and initialized with character y .
Line 7: Next line clears the any previous output from output screen.
Line 8: The eighth line prints a line informing user that if he needs to close this program then he/she should press Capital X.
Line 9: Next line is a while loop which keeps looping fpatagonia guide pants are dragon1our lines in it until we press X.
Line 10: Beginning of while loop.
Line 11: In this line of code we store the ASCII value of key pressed by user during runtime. For example if user presses p key on keyboard then its corresponding ASCII value, 113 gets store in ch variable.
Line 12: The sound() will produce sound from pc speaker and in bracket we need to set frpatagonia better sweater coat smallequency at which it will buzz. Here wepatagonia better sweater wax red are multiplying patagonia clothing store locator10 with ASCII value available in ch variable. You can change the constant 10 in this line to different integepatagonia guide pants are dragon2r value and as a result it will change the sound output. Do experiment only with this value.
Line 13: Here delay() function determines how long the sound will last (Note: actually delay() function suspends the execution of program). This is determined by value provided in bracket. In our example I havepatagonia everlong review doctors set 75 milliseconds. If you change it to 3000 then sound will be played for 3 seconds.
Line 14: The nosound() function works opposite of sound() function. It turns off PC speaker. If we won t use this in our program then speaker will keep buzzing until we close program.
Line 15: End of while loop.
Line 16: End of main() function.
