But before I have to solder the pins. Do you have any advice how to do this, so that the shield fits afterwards onto the arduino?
And the general question is: what do you do, if you use shields with pin conflicts? E.g. PWM/3 seems to be a popular pin on many shields. So do you change shields with knife and soldering iron? Or is there any other magic?
I like to put the header pins into a breadboard and then put the board on top of that. Solder a single pin to orient the board and pins to 90°. After that I solder every other pin taking 10-15 seconds between pin to allow them to cool and keep the breadboard from getting too much heat.
That's one way. You can also use a shield made to be cut up like this one:http://www.amazon.com/Add-Ohms-Arduino-Wuzzler-Shield/dp/B007APUR3I/ref=sr_1_1?ie=UTF8&qid=1335556644&sr=8-1
I will post the pictures of the result this evening in my little blog.
