The 555 timer breadboard signal generator DIY kit

This listing is for a DIY 555 square wave generator kit that can fit directly into your breadboard, based on how you choose to build it.  The video above shows you how to put this kit together, how to potentially modify this kit, and how to use this kit.  The circuit is based on an NE555 timer set up in astable mode, and can output roughly 3.5Hz - 1.2kHz.  It is a very easy kit to put together.  There are four pins on the board:

VCC:  4.5v to 15v supply voltage pin

RST:  Reset pin.  This pin can be left floating.  If you choose, you can ground this pin to disable the output of the 555 timer.  

OUT:  The output pin of the 555 timer.  This is where you'll see a square wave.

GND:  DC Ground.  

The data sheet for the NE555 can be found here:  http://www.datasheetcatalog.com/datasheets_pdf/N/E/5/5/NE555.shtml

When you purchase this kit, you will receive the custom PCB, and all of the components necessary to build this kit into a module.  It does not come with a hard copy of instructions.  the video above will offer you all that you need to create this kit from scratch.  Please let us know if you have any questions at all.  We are more than happy to answer them.
