Hello, I want to make a speaker play music from a MicroSD card. Some tutorials showed only the MicroSD card module, BD139, and a speaker. Some people said this will fry my board or that I will need an amplifier. Can someone help with the components I need and maybe a schematic? ---

To get decent audio output (as opposed to just a beep or crude sound) you will need an amplifier. Something like this > **[OPEN-SMART 8002A Mono Audio Power Amplifier Module for Arduino MP3](http://underpop.online.fr/o/open-smart-8002a-mono-audio-power-amplifier-module-for-arduino-mp3/)** > **[Adafruit 20W Stereo Audio Amplifier - MAX9744](https://learn.adafruit.com/adafruit-20w-stereo-audio-amplifier-class-d-max9744/digital-control)** > > Pump up the volume with this 20W stereo amplifier! This slim little board has a class D amplifier onboard that can drive 2 channels of 4-8 ohm impedance speakers at 20W each.

Here is a similar circuit based on ATTiny microcontroller. > **[One-transistor audio amplifier for Arduino projects](https://bryanduxbury.com/2012/01/20/one-transistor-audio-amplifier-for-arduino-projects/)** > > For my recent Question Block Lamp project, I wanted to be able to play sound effects. Initially I was a little concerned that it would be difficult, but after I found the awesome Mario Piano Sheet … I tried the same using Arduino UNo and a 2n2222. It worked. ---

Yes it will work but if you turn the volume all the way up, the music will be very distorted and you may damage the speaker. ---

Good choice Jim! Anyone who thinks a 1 transistor amplifier will do the job hasnt done the sums. ---
