Share this: This project illustrates the use of a microcontroller (MCU) to generate different types of sound. The device uses SST89E54RDA-40-C-PIEMCU, an 8-bit 8051-compatible MCU with embedded SuperFlash memory.The device comes with 24/40KByte of on-chip flash EEPROM program memory which is partitioned into two independent program memory blocks. The …

This concept has been used to generate sound from the microcontroller. Varying the frequency can produce different types of sounds especially with the use of timer 1 of the MCU to produce different frequencies. Timer is used to produce exact delays and by toggling the output pin, it will generate the desired frequencies.
Audio Tone Generator using AVR Microcontroller
https://atmega32-avr.com/audio-tone-generator-using-avr-microcontroller/
The output of Microcontroller is always digital so to generate audible sound at the outset first it needs to be converted into Analog. A DAC (Digital to Analog Converter) is used for this purpose. Microcontroller generates sine wave of Audible Frequency using DAC. This sine wave is further given to Audio Amplifier that drives speaker.

Generating an audible sine wave and producing its sound in a Loud Speaker is the first step towards using the microcontroller in audio applications like media player, announcement system, record and playback etc. The PIC18F4550 has four PWM output channels and they are P1A, P1B, P1C and P1D. All of them are capable of generating PWM waves at a time.

Inside the loop, we first set the output pin on the microcontroller to HIGH (1), then we wait for half the amount of calculated period & then set the output pin to LOW (0) and again wait for half the amount of calculated period. This way, we are operating at 50% duty cycle. Here is a simple output audio I created using the above method

Set up a timer ctc int at this freq. In the handler count x,y,z number of ints to get a half cycle. Turn ea output on/off in handler. Actually we want to generate three frequencies using combinations of following DTMF frequencies and these frequencies should vary at various programming interactions.
