Introduction: Solderless Breadboard Layout Sheets (plug and Play Electronics)
Here's a fun system designed to take care of some of the headaches involved in breadboarding a circuit.
It is is a simple set of template files drawn to scale with real world electronic components.
Using a vector drawing program you simply move the components onto the breadboard template, draw a few wires and print the result (if you're old school you can print the template and use scissors and glue).
Pin the template to your breadboard, place the components and wires, and you're good to go. Better yet if a wire later falls out its easy to pop it back into place.

The Component Library can be found here
The Circuit Library can be found here
Like the breadboard layout sheet idea and looking to play around with an Arduino? we make a fun kit that combines the two. (in the UK it can be purchased here anywhere else in the world it can be purchased here)

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Software
Option 1 - Inkscape (modern)
Inkscape is an Open Source vector drawing program. Its a little rough around the edges at the moment but it is only getting better, and when looked at in its entirety pretty impressive.
- Download Inkscape from inkscape.org
- Download the component library in Inkscape (.svg) format on the next step
- Copy and paste components and move them around (use the arrow keys the nudge is set to 0.1" so you're components will all stay alligned)
Along with the Inkscape format all the files in this instructable are also available as .pdf. What this means is you can download the PDF print it out and then use old fashioned glue, scissors and pen to make your templates. Or you can also download pre-drawn circuits from step 3.
Step 2: Component LIbrary
The current set of components is a bit of a random selection of those we've found useful around the .:oomlout:. offices. More will be added as we draw them.
If you've drawn a component for we'd love to have you share it here (send us a message if you'd like collaboration privelages, or simply e-mail us the file and we'll integrate it into the library)
Current Component List
Breadboards occasionally vary in how they align their power strips, we currently have two supported layouts

Step 3: Circuit Library
Here are a few we have used around our offices. (appologies at the moment they are solely Arduino based but we are working on a set to explore more general electronics principles)
(If you draw a circuit we'd love if you'd share it here (send us a message if you'd like collaborator privellages or e-mail us the file firstname.lastname@example.org)
