ATtiny2313 microcontroller circuit with MAX232 PC connection can be established based on the pc program with wav file loading the output of the power amplifier TDA2003 integrated amp
Atmel Wav Player Circuit Test
The electronic circuit it ATtiny2313-mas* mikrovezérlo that of a circle is being built. AVR-hez* the memory IC (AT45DB4161) a voltage divider is attached with resistances since the memory is a maximum 3.6V-ot* is able to tolerate it. According to this Z-diódás with a stabilizer 3.3V-ra* the supply voltage is portrayed for IC. From IC it adatvzeték* the AVR re is attached directly since he is AVR the 3.3V-ot* H can perceive it as a level yet.
The digital code being equal to the sound AVR single R-2R turns it into an analogous sign with a network, mainly the cost effectiveness and I decided it because of the simplicity at this solution. The strengthening grade follows this. For strengthening IC TDA2003-mat* I singled it out mainly his plain connection, his price, and the equivalent, cca. 10W-os* because of his leave performance.
To put on a sound for the apparatus, to delete we are top notch with the help of a computer. The electronic circuit sorosporttal* is attached to the computer, this an MAX232 type next fitting accomplishes it through IC
