Arduino Shield

This can be the basis for all sorts of Arduino projects when you want to add extra components. I prefer to do this using strip board and solder rather than solder-less breadboard. I find the solder-less approach big bulky and very impermanent. What makes this project a bit less than easy is the fact that all the connectors are not on the same 0.1” grid. Is this a cock-up on the part of the original designers or is it a ploy to get you to buy a printed circuit board to do your prototyping on? Or is it a feature that stops shields being plugged in with the connectors misaligned? I don’t know but I always favour the cock-up view of history rather than the conspiratorial.

Anyway the trick to making a shield is to drill a row of eight 0.8 mm holes between the holes on the regular pitch of the board. This looks tricky when looked at from the top side but if you look underneath you will see it is relatively easy to put these holes between the copper strips. Now if you just soldered the strip line pins in these new holes they would shirt out, so the next stage is to cut away the copper on the left hand side of the new holes with a sharp knife in this way you only solder to the one strip. Next mount the strip pins in the Arduino and place the strip board over the top copper side down. Go in from the side and tack (with solder) the first and last pins on each of the four strips. Now you can remove the strip board, turn it over and make all the solderd joints properly. Make sure you go over the tacked joints last. In this way you will have a prefect fit between your shield board and the Arduino. That’s it all the remains to do is to build your circuit on it.
