Lining up the LED
We are almost ready. Now it is time to decide how to connect the LED (
D3
) and where to drill a hole
in your enclosure. I used and old enclosure I had lying around (BYOC, how fitting) so it does not really
represent how tight you can build this! I will describe the procedure of fitting the led directly on the
PCB, but you can always decide to do it differently eg. by using a Led flange.
1.
Start by drilling the hole for your switch (approx. 15 mm from the bottom, but measure and
decide before you start drilling!!).
2.
Stick some double sided tape to the right of the hole and remove the sticker revealing the
sticky side.
3.
Insert the LED in the board (bottom side!) , but do not solder it! Orientation of the LED is not
yet important as we are only going to use it as a placeholder for measurement.
4.
Insert the PCB in the enclosure while holding the LED so it does not fall out. Place it the way
you fit right and press the led so it sticks to the double sided tape.
5.
Now gently pull the board with switch out, making sure the LED sticks to the tape.
