Could be a project for you later on
Why do you have so many connections though?

Why can't you just use the direct connection to the Pi? Do the boards just give you more pins effectively? So I can use the pins directly, and only need an extra board if I wanted to connect more things (Which I don't).
You are asking why have I got so many pin's
On my interface board. The same reason
Is that they have 26 pin's on the Pi header
Out put . I designed the interface board
To be Multi Tasking ( Different Projects)

You are asking questions with out thinking

@7ewis:

I think it's time to take a step back: you have a project to do for someone else in the next couple of weeks.

You have no knowledge of electronics even at the most basic level of what the pins on GPIO, how to use them. When people provide help, you ask further questions, or repeat previous ones.

You have no soldering skills yet want to use a surface mount transmitter.

There are two possibilities I can see here:

1 - you need to learn a lot more before you can achieve this project, and that's going to take more time than you have.
2 - you are a troll

IMHO, I choose 2 and will not waste any more of my time on this thread. I'll leave it to others to make their own decisions.

I totally agree with the post by Hove
You are totally out of your DEPTH
Donate your Raspberry Pi to the
To the local school, At least you will
Have achieved something , If they ask you
To help with a project they are doing
Just make a quick exit.

I think we've missed the 'explain like I'm 5' part of OP's question, and the fact that they only have 1 project they want to do.

Let's keep it friendly pls - I'll try to write a post soon if I get the chance

Bah, after reviewing the thread, I'm as annoyed as the others...

Here is your simple answer, explained like you're fiveish.

Buy a dupont wire of over 16cm in length, such as can be bought from here: http://www.amazon.com/40PCS-Dupont-cabl ... B007XPSVMY

Cut the wire to 16cm length

push the plastic connector end onto the Raspi Gpio pin 4, as is shown in this picture: http://www.skagmo.com/temp/content/proj ... o_1200.jpg

follow the instructions from http://www.skagmo.com/page.php?p=projects/22_pihat : namely:

Code: Select all

wget http://www.skagmo.com/content/projects/22_pihat/pihat_0.1b.zip
unzip pihat_0.1b.zip
cd pihat
chmod +x pihat
Put your Nexa receiver in pairing mode


Transmit a long signal at the desired ID and channel:

Code: Select all

./pihat --repeats=50 --id=1 --channel=0 --state=1
After a successful pairing operation, transmit eg. an off-signal:

Code: Select all

./pihat --id=1 --channel=0 --state=0
Get to know the syntax by typing

Code: Select all

 ./pihat --help.
[/i]
Also, please, lurk moar...

For solder-free electronics, there is stuff like crimp connectors, electrically conductive glues that you can make or buy, and the aforementioned Dupont wires, which could be held on with tape or glue..

Also an old floppy drive ribbon cable fits the gpio header quite nicely. You must be *very careful* about knowing which wire goes to which pin though, and avoid letting the wrong ones/any of them touch, otherwise you could easily fry your pi...

For prototyping a circuit generally a breadboard is used, you can use a pibow gpio connector + breakout board, soldering is used for a permanent circuit and connecting wires to modules, as for the web server bit I know very little, I mainly do electronics.
