- Start with a mp3 (music module ) about $4.00 online. It has some weird pinouts, but you can ignore most of them.
- You need to connect VCC and GND to the Arduino power and ground circuit.
- and SPK_1 and SPK_2 go to the speaker
- Finally the mini SD card must contain a sound file name 01.mp3 and this is turned on by the Transmit and Receive connections ( TX and RX)
- Sample codes and how to use the module are here!
- how do we insert a brighter LED into the "Evil Teddy"?
