# foil circuits
|
|
|
|
The large holes at the bottom of the board are designed to attach alligator/crocodile clips
|
|
to create electrical circuit with other components.
|
|
|
|
If you do not have crocodile clips at hand, dyou can use wires or even Aluminium foil to acheive the same result.
|
|
We will show you how to connect the micro:bit to headphones using Alumunium foil and tape.

### Materials
|
|
|
|
* micro:bit and battery pack (you can also power it via USB)
|
|
* a small piece of cardboard
|
|
* Aluminium foil
|
|
* tape
|
|
|
|
### Assembly instructions
|
|
|
|
Tape the micro:bit and battery pack to the card board. Make sure to remove the batteries while you are building your circuit.
|
|
|
|
|
|
|
|
Cut the thinest strip of foil possible and roll it into a cable. You can also try to fold, whatever works for you.
|
|
Build two of those wires.
|
|
|
|
|
|
|
|
Place the foil wire on the ``GND`` pin and attach with a piece of tape. Press hard to get the best connection between
|
|
the foil and the pin board. Make sure the foil is not overlapping with the other pins!
|
|
|
|
|
|
|
|
Place the second wire on the ``P0`` pin the same way. Make sure the wire does not overlap with the other pins!
|
|
|
|
|
|
|
|
Tape the headphone jack connector to the cardboard and roll the wire coming from ``GND`` around the metal base.
|
|
Make sure the wire does not touch the other metal rings on the jack.
|
|
|
|
|
|
|
|
Tape the second wire on the head of the jack connector.
