Step 1: Parts
1x LM386 amplifier chip
1x 100nf capacitator
1x 100µf capacitator
Step 2: Assembling
insert the LM386 chip into the prototipyng board and solder a wire to pin 6 of the ic and connect it to positiv 9Volts then add a 100µf Capacitator to pin 5 (+ to pin 5) and connect a speaker to the - terminal of the capacitator and connect the speaker to GND.
Next, connect pin 4 with a wire to ground
then connect the 100nf capacitator to music input (connect channels Right+Left together and ground from the audio to ground)
