SparkFun Barrel Jack Power Switch - M-F (3") Buttons/Switches, SuppliesWe use barrel jacks a lot around here and sometimes we need to pop a switch into the mix. That usually means hacking up a perfectly good barrel jack extension cable, but the whole point of using the barrel jacks was so that we wouldnt have to hack things apart Well, we found a solution: The Barrel Jack Power Switch. Okay, its nothing fancy but it is really useful. Plug your power supply into one end and the other into your project and, just like that,

is the same one found in digital bathroom scales (you know

these probes are great for testing your SMD components

It has 7 power buses

Solder on your wires and crimp the strain relief to make a finished

To prevent a 9V from accidentally being attached to the 5V board

The LilyPad Arduino consists of an ATmega328 with the Arduino bootloader and a minimum number of external components to keep it as small (and as simple) as possible

Do you have some liquids that you need to move

breadboard friendly

Often used for reverse voltage protection

This will allow you to use Arduino code in your custom embedded project without having to use an actual Arduino board
