Pots, wobbly breadboards and wiring


My project involves a lot of potentiometers. I am still at the noobie breadboard stage and get very variable responses from the pots - when I can stop them falling out of the breadboard that is! I think I am going to need to progress to soldering wires to them and making a more 'permanent' testing solution.

I was planning to solder them via wires to header pins, but these too can wobble in the breadboard. Can I avoid soldering them to a DIL socket that holds the different ICs (595's etc) or will this be necessary, in place of actually designing a fully-blown PCB?

Also, what quality wire is best for wiring 10k pots to the ICs?



HI, Flakey connection problems are one of my unfavorite things with Arduino ..

That's one reason why I like secure cabled connections to things, especially for workshops/classes.

Take a look at this on cabling: http://arduino-info.wikispaces.com/Cables

And the easy way to connect is with cables to an Arduino with cable type connectors like this: http://arduino-direct.com/sunshop/index.php?l=product_detail&p=225

Or a Sensor Shield plugged on top of an existing Arduino like this: http://arduino-info.wikispaces.com/SensorShield

Pots are a problem. Which type do you have?? It took me a while to find these which plug into the breadboard pretty well: http://arduino-direct.com/sunshop/index.php?l=product_detail&p=184

...but if you are going to end up with some panel with the pots in it, maybe it's time to drill holes and mount them.. You could cut one end off these: http://arduino-direct.com/sunshop/index.php?l=product_detail&p=194

or this: http://arduino-direct.com/sunshop/index.php?l=product_detail&p=185

...and strip and solder them to the pots, and plug the other end into Arduino sensor shield or arduino+3-pin connectors...

OR, for a few, these pluggable pots are easy to use and have secure cable connections: http://arduino-direct.com/sunshop/index.php?l=product_detail&p=34

Let us know how it goes!

Thanks for the pointers!
