Procedure:

• Connect the header pins to the DF Player mini and insert the setup to our PCB as shown below

• Now solder the header pins with our soldering iron, be careful while doing soldering.

• Take the FM-16p speaker and solder the two input terminals of the speaker to the mini player as shown in the figure below

• Put the FM speaker in the plastic box for the audio amplification.

• Connect the momentary push button to our plastic box for changing the output. The push button is used changing the output by triggering the input from the external source. The audio amplification of the circuit is done by connecting the speaker directly to the power source.

• Now connect the LED light to our circuit for getting the signal about its present condition. If the LED light flashes indicates the ON condition and vice versa for the mp3 circuit.

• Connect the power supply to our circuit, after a moment the LED start flashing represents it working condition.

• Cover the plastic box carefully without breaking any connecting wires. Now we can enjoy the best melody music and chill our self with our self-made mp3 player having beautiful amplification and bass.
