10pin programmer on breadboard for $50 robot

[knightofarmor]

I am trying to assemble my circuit on a mini breadboard.  All has gone well so far but I just realized I will not be able to place 2x 5pin headers on the board without them making false connections.  How would I do this?  If this doesn't make sense or you have any questions, let me know please.

what do you mean by "false connections"?

sadness wat do u exactly mean.. ?

On bredboards, the connections work in lines as shown on this website: http://www.kpsec.freeuk.com/breadb.htm

According to the schematic, each pin from the programmer should be connected somewhere.  If I were to attach 2x 5 pin headers to the breadboard, so I can attach my programmer, then I would have unwanted connections because each line is connected.

If this still doesn't make sense, I can draw it out or re-word it somehow.

cant you place them somewhere else on the board? like in attached image, then jumper some connections? not all lines on a breadboard are connected just the ones with blue/red/black lines through them.

You will have to construct a breakout board which converts the footprint of the connector. Using stripboard/veroboard would be a good idea.

Just cut the 5 tracks in between the holes you will solder onto, solder the 2 rows either side of the cuts (so that your pins aren't connected). Then solder some inverted pin headers either side of the 2x5 connector (see the picture attached). This will be the perfect size for breadboards. Having two spaces between the inverted pins makes them spaces the same distance apart as a small PDIP package.

To invert the pin headers (so they stick out from the bottom of the stripboard) you just use some pliers to push the pins further through the plastic.

Sorry if the wording is bad... ill rephrase it if need be

This wouldn't work because every pin on the programmer needs to be wired somewhere.  Since the blue lines are all connected this would mean both connections would go to the same place.  Look at it this way.

In this example, each line is on the same connection.  If I wanted 1 from column A to connect somewhere, I would attach a wire in the hoe directly above it and the other end of that wire wherever it needs to go.  Now If I wanted 1 from column B, to go somewhere, I can do exactly the same thing.  But, since the entire line is connected I would have both, 1 from column A and 1 from column B, going to the two exact same places hence creating a false and unwanted connection.

easier way to "invert". grab the plastic part and push down hard. you are looking for something like the attached.
and to the other question, look at the attached. jumpers jumper to pins on the chip.
purple is the programmer header.
cut where the red line is to un-connect the holes.

im confused

[hazzer123]

It would work... sorry if my explanation is rubbish. Ill draw a picture

Red are strip cuts (to stop the connections you fear...)
Blue is your 2x5 connector.
Green are the inverted pins.

This would fit in a breadboard across the gap in the middle where chips are meant to go.

An easy way would be to just soler 10 (or however many you need considering some of the pins are conected) wires to the 10pin header and just have them running a short distance to the breadboard.
