Wiring an LCD shield

Former Member

Hi Everyone,

I'm new here and just purchased the lcd shield from dfrobot.  Now that I've finished the programming I'm ready to connect some inputs.  I need to use digital pins 10-12, 5v and ground on my arduino uno.  I'm sure I have to solder the connection on the lcd shield, but I want to make sure before applying the heat (I have very limited experience with soldering).  I was hoping to find a video show exactly how to do so, but have not found anything on youtube.  Can someone help me out?

 

Thanks,

Onyx

    If you have a temperature controlled soldering iron, set it to between 600F and 650F.  Be sure the tip is hot enough to melt the solder before trying to use it.  Wipe the tip on a damp sponge or paper towel to get rid of the oxidized solder then wet the tip with a little solder.  Place the tip next to the wire on the pad at the same time and apply the solder.  Don't hold it on any longer than 5 seconds.  Don't put so much solder on that it balls up.  Just a little more than enough to fill the hole.

    Adafruit has one of the best tutorials I've seen.

    It explains what the tools are, then a couple of pages in shows the process in detail.

    Many beginners forget to heat the surface that the wire has to attach to, and hence have problems.

     

    You'll need to strip and then twist the wires before 'tinning' them. (Tinning is applying solder to the wire.)

    Cut them to a suitable length as the insulation sometimes shrinks back.

     

    I would also suggest you apply a little solder to the shield pins, and then add the tinned wires.

     

    You can practice on something else first.

    The secret is not too much heat on the wires. If it isn't going right, stop and let the joint and wire cool down, then try again.
