hello guys.i want know if adafruit fx audio mini sound board without amp or headphone jack on board. can provide direct input powered (mono) speaker, or require amplifier?.. because don't if still need buy amplifier. , wattage of speaker can handles. im sorry im new kind of stuff. thank in advance answering question.

can provide direct input powered (mono) speaker, or require amplifier?..
powered computer speakers , powered studio monitors have amplifier built-in.   a raw speaker/driver needs amplifier.   stereo/hi-fi speakers need amplifier.

if want build amplifier, there lots of "power amplifier" chips, or can buy assembled amplifier pc booard.    if buy board, you'll need add power supply, volume control, , you'll want case.   

or can buy small amplifier (that 1 doesn't come wall-wart power supply) or bigger amplifier.

and wattage of speaker can handles.
that gets complicated.    "small project" can get-by less 1 watt.   a tv puts-out less 10w.   a "standard factory" car stereo might put-out 10-20w.    home stereo/home theater system have more 100w, of time won't listening loud.

of course there volume control, , because have 10w amplifier, doesn't mean have listen @ 10w full power.

the speaker's power rating "peak program power".    example, if listening regular voice or music 10w amplifier , a10w speaker stereo loud can go without distortion, hitting 10w on peaks it's 1w average.  means 10w speaker can handle 1w average fry constant 10w test tones, or if make 10w siren, etc.

and, power rating speaker it's maximum rating...  it's ok use 100w speaker 1w amplifier.

quote
can provide direct input powered (mono) speaker
most computer speakers stereo.   you can connect left & right inputs mono (the same sound both speakers) or left or right can unplugged don't have use it.   you can buy single "mono" studio monitor.

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
