Creating the Seventh Routing
The last step is actually pretty complex, and has another opening for the speaker/output component:
To do this, we have to use the large, black capacator, and to pay attention to which way the negative leg is connected. In the circuit diagram, the positive leg of the capacitor is shown. However, if you look at the capacator, you'll see that the negative leg is the one that is indicated. Make sure that you put it in the right way, then leave a space for the speaker to be connected:
Check your work before the next connection - if the capacitor is put in wrong, it could 'blow'!
Once you've check the work, connect the speaker to the two columns created in this last step:
If everything is correct, you should hear your circuit sing! If not, we need to do some debugging...
