ECTE333 Microcontroller Architecture and Applications
Lab 4, Task 3 (demo) and Lab 6, Task 1 (coding)

Here, we use ATmega16 to produce a musical tune on an audio transducer.

• The audio transducer is connected to pin D.6. The audio transducer accepts a digital square signal, and it generates sound waves at the same frequency as the input signal.

• A musical tune is considered as a sequence of square waves that have defined frequencies and durations. For example, the frequencies and durations for the “Happy Birthday” tune are as follows.

Frequency(Hz): 262, 262, 294, 262, 349, 330, 262, 262, 294, ...
Duration (ms): 500, 500, 1000, 1000, 1000, 2000, 500, 500, ...
