The WCRS version of the ARDX experiment instruction pages include links to Fritzing sketch documents. The schematic and wiring layout images have been generated from the program, usually with a little after the fact tweaking to add or repair things that the application does not currently handle well.
In the process of creating the experiment sketches for the web pages, additional parts that were not (then) part of the core library, were needed. There were created as needed. If you just want to work with copies of our fritzing sketches, there is nothing extra that needs to be done. The custom parts are included as part of the sketch document.
However, if you want to create your own sketches from scratch, those extra parts could be useful. Links to them are supplied here, along with a few notes about when to use them. To use one of them, down load it to your local machine, then open it in Fritzing. That will add it to the "My Parts" bin. Remember to save the imported parts, and the "My Parts" bin updates, if you do not want to have to import it again each time you need it for a new sketch.
This should never be needed for new sketches. Unless you are creating a new circuit that is be added to our ARDX pages. It has no electronic functionality. The physical header is used to hold the paper breadboard sheet in place when building the circuit from the ARDX documentation. The part is only used to make the generated images look more like the breadboard sheets for the original ARDX documentation.
This is an adapter part, that allows a 2 row male header to be plugged in to a breadboard. The physical part was custom built as well. It is just 2 headers with long pins¸ that are normally used to build arduino shields. The pins are bent, near the body of the header, about 45 degrees 'outward'. then, about ⅓ cm further down the pin, bent 45 degrees in the opposite direction. The result is a header where female socket connections are offset about 0.1 inch sideways from the pins. 2 of those 'back to back' will fit across the centre of a breadboard, fitting in the same position as a DIP chip would. The header sockets are then adjacent, and a 2 row header will fit in them. This was initially created to connected an nRF24L01 radio module to a breadboard. It is a lot more (physically) stable that way, than running 8 separate wires. It also means that only the standard ARDX kit male to male dupont jumper wires are needed. No male to female jumpers are needed.
The fritzing part provides the same functionality for sketches. Placing the adapter part across the centre of the breadboard allows an nRF24L01 module (see below) to be placed on the header, and jumper wires connected to the breadboard view correctly create connections on the schematic and pcb views.
Like the main breadboard, a part inserted in the header will move when the header part is moved. However, the pins from that part do not get reconnected to the underlying breadboard when the adapter is positioned again. To get the connections back, the parts in the header must be moved out and back again. This seems to be a limitation of the way the Fritzing program works.
This is the standard relay included with ARDX kits. The part has been configured with schematic subparts for the energizing coil, and each set of the double pole switch contacts. That can make the schematic simpler. The circuitry to control the relay coil often has very little to do with the load being controlled by either or both of the switches.
This is a version of the radio we have been using for the CarBot. This version has the antenna built into the printed circuit board. The version with the external antenna has exactly the same interface pins, so this can be used in Fritzing for either module.
This is a recreation of the core "DIP-Relay-D31A" part. I needed a part for a 941 series relay, and this was a working example to start from. In the process, the original part was rebuilt with a different schematic view that supports sub parts. The relay switch contacts and shield connection are movable independent of the energizing coil.
