Step 15Complete the circuit.
Now it is time to finish off the circuit by adding the remaining components.
First attach the audio cable.
Only one speaker is connected directly to the board. The other speaker and the power source are connected at the other end of the headbands.
As such, both headbands are connected directly to the board. On the other side of one headband should be a speaker. And on the other side of the second headband should be your power cap. These will go to the left ear. Make sure you got your wiring right.
Once this is done, plug it in and see if it works.
If it does not work:
- check your wiring
- see if the chip is still working
- check your soldering
- make sure no connections are bridged
- make sure the wiring is right
