MEMBUAT LAGU TWINKEL TWINKEL LITTLE STAR DENGAN ARDUINO

ya kawan di sini masih dengan pembelajaran dasar Arduino tetapi menggunakan buzzer ini masih sama dengan yang lagu mario bros tetapi berbeda dalam Coding nya
 bahan dan lay out masih sama seperti yang di mario bros
jika anda lupa coba lihat layoutnya di sini https://elementertech.blogspot.co.id/2017/01/membuat-lagu-mario-bros-dengan-bazzer.html

dan ini program nya :

/*

	Use Freeduino-RichBoard made by www.EmbeddedMarket.com
	1. Connect Digital Pin 9 to Buz pin in Section 9 on Freeduino Board
	2. Connect USB Cable

	*
	* This example uses a piezo speaker to play melodies. It sends
	* a square wave of the appropriate frequency to the piezo, generating
	* the corresponding tone.
	*
	* The calculation of the tones is made following the mathematical
	* operation:
	*
	* timeHigh = period / 2 = 1 / (2 * toneFrequency)
	*
	* where the different tones are described as in the table:
	*
	* note frequency period timeHigh
	* c 261 Hz 3830 1915
	* d 294 Hz 3400 1700
	* e 329 Hz 3038 1519
	* f 349 Hz 2864 1432
	* g 392 Hz 2550 1275
	* a 440 Hz 2272 1136
	* b 493 Hz 2028 1014
	* C 523 Hz 1912 956

dan setelah itu saya ucapkan selamat mencoba dan semoga berhasil :D
