hi, Reason i am writing this is because i want to be able to play mp3 sound on my robot i know that ez-b has support on sparkfun mp3 trigger but it is too expensive it cost 50dolar+shipping is there another way to play mp3 sounds on my ez-b, a simple circuit maybe or another cheaper device that will do what i want thanks and cheers
You will need to either use an MP3 board, amp & speaker or use a bluetooth (or other wireless) speaker. There are no other ways of doing this.
I use these from MDFly with a cheap 3W amp from E-Bay.

thanks lumpy i have a quest,on about that product is it enough if i connect only gnd,rx,tx to ez-b thanks
You can get by with Rx/Gnd/3.3V
thanks while using the trigger i think i will install it like installing sparkfun version
in ARC mp3 trigger
it says
board port baud
lets say i will connect the trigger to d1 port what is the setup for board and baud rate thanks
and where do i connect my speaker thanks
So once you have this board and a small amp you will have the following connections:
Soundboard/Amp -> EZ-B (RX/GND/3.3V) Amp -> Speaker
It uses serial command lines:
SendSerial(D1, 9600, 0x01) -> Plays Track #1 SendSerial(D1, 9600, 0x02) -> Plays Track #2 SendSerial(D1, 9600, 0x03) -> Plays Track #3 and so on.
Search the forum, they have been discussed here.
Amp from E-Bay that I use.
