Arduino + Wav Trigger + 2 Audio Amplifiers MAX9744

-

i building interface series of audio samples (as wav files) played robertsonics wav trigger.
this board has mini-stereo jack use in order control 4 speakers.

the max9744 amplifier can control 2 speakers , thought perhaps control 4 speakers using 2 amplifiers. think?
what type of splitter need in oder send same stereo signal both max9744s?

the interface building pretty small , avoid using classic mixers.
is there board or build myself?

thank help!

splitting opposite of mixing , it's ok hard-wire 2 inputs together.   regular y-splitter work fine.


...you should never directly connect 2 audio outputs  together.  for need mixer (although can make simple passive/lossy miser resistors).    and, have careful multiple speakers same amp because of impedance load.

hi new arduino , trying write code of temperature controlled fridge can adjust pot , temp in fridge changes lowest setting -15 , highest setting 30degrees. the temp drops below input pot im trying make compressor turn on , light show compressor on. new @ , im still not quite sure im doing. error below keeps popping , im not quite sure whats wrong code. im hoping on close path how should have done it, how fix error appreciated. arduino: 1.8.4 (windows 10), board: "arduino/genuino uno" c:\users\admin\appdata\local\temp\ccfcxdpc.ltrans0.ltrans.o:(.rodata+0x6): undefined reference `print::write(unsigned char const*, unsigned int)' c:/program files (x86)/arduino/hardware/tools/avr/bin/../lib/gcc/avr/4.9.2/../../../../avr/lib/avr5/crtatmega328p.o:(.init9+0x0): undefined reference `main' collect2.exe: error: ld returned 1 exit status exit status 1 error compiling board arduino/genuino uno. this report have more information with "show verbose output during comp

esp8266 (nodemcu 0.9) client.write très lent ???

bonjour à tous, j'essaie d'établir une communication entre une carte nodemcu exp8266 et mon pc en wifi via les sockets wifi. cela fonctionne plutôt bien mais le problème vient de la lenteur des instructions liés à l'écriture : par exemple client.write(buf) qui s'exécute en 200ms et est donc bloquante. comment peut on faire pour réduire ce temps d'écriture car c'est vraiment handicapant. merci a+ antoconde vous êtes sous windows? si oui c'est sans doute dû aux delayed acks quote if make network trace network sniffer such microsoft network monitor, tcp server sends tcp ack segment last tcp segment in tcp data stream in delayed acknowledgement timer (also known delayed ack timer). default, windows operating systems, value timer 200 milliseconds (ms). faut éventuellement gérer l'agrégagtion d'ack dans votre code pc en contournant les infos systèmes. ça améliorera un peu les choses - mais le problème est côté pc pas esp (pa
