i'm having a slight issue with my mp3 shield.
Now i accept that i'm a noob in the wonderous world of arduino, but i'm pretty sure it's not me.
I've figured out how to get the shield to play music over the headphone jack, but when i use the direct speaker outputs it wont make a peep.
I've tried holding the speakers leads against the headphone's jack contacts and it plays very softly (even with the volume on 1, 1)
but when i press the leads against the speaker ports or solder them in place, it doesnt work.
so the actual questions.
- Do i have to change anything, either in the code or in the solder connections on the board (like a jumper)
- Do i have to use the terminal connectors shown on pictures, because i assumed making a simple solder connection would work just as well.
Here is the code i used, its the standard code with a slight change to the "Shield to breakout board" and the volume is set to 10
I use the code on a arduino Uno, so the solder jumpers should remain open according to the tutorial
