-The large holes at the bottom of the board are designed to attach alligator/crocodile clips.
-Register an event that will execute whenever the user attaches one side of the crocodile clip to the `GND` pin, then connects and disconnects the unattached side of the crocodile clip to pin `0`, `1`, or `2`.
+The large holes at the bottom of the board are designed to attach alligator/crocodile clips 
+to create electrical circuit with other components.
 
-### Example: on pin pressed with random numbers

-This example displays a random number every time the crocodile clip holds  `GND` then connects and disconnects the `P0` pin. Each time the crocodile clip is firmly connected and disconnected from pin `P0`, the micro:bit will return a random Number between 0 and the parameter limit

+The hole for ``P0`` and ``GND`` allow to grab the board on the side which makes for a great grip.

+
+For the center holes, ``P1`` and ``P2``, you can also grab the bottom of the board but they are a bit harder to grip.
+
+You can also grip the board between the jaws. In which case, you will want to make sure to avoid overlapping the jaws 
+with the other pins as it will create short-circuit in the board.

 # Error codes
 
-The micro:bit error codes
-
 Your micro:bit may encounter a situation that prevents it from running your code. When this happens, a frowny face will appear on your micro:bit screen (see picture) followed by an error number.

+# 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.
+
+https://youtu.be/mhXYyPuvpz0
+
+### 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.
+
+![](/static/mb/device/croc-clips/microbitattached.jpg)
+
+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.
+
+![](/static/mb/device/croc-clips/foilcut.jpg)
+
+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!
+
+![](/static/mb/device/croc-clips/groundconnected.jpg)
+
+Place the second wire on the ``P0`` pin the same way. Make sure the wire does not overlap with the other pins!
+
+![](/static/mb/device/croc-clips/microbitconnect.jpg)
+
+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.
+
+![](/static/mb/device/croc-clips/jackground.jpg)

+Tape the second wire on the head of the jack connector.
