This exciting Solderless kit lets you build a Digital Touch-Activated Switch circuit using a 555 Timer IC as a Mono- Stable Multivibrator to generate a pulse. This pulse will be sent to the 4029B Up Down Div/10 IC and the output will be connected to a LED. The LED will turn on and off as you touch the contacts.

Touch it on, touch it off. This Circuit will turn on the LED light with the touch of your finger and turn it off with a second touch.

Full color instruction manual makes this kit easy to build while explaining the theory of operation. Kit includes all electronic components and the solderless prototype board needed for completion.  The solderless prototype board can be used over and over again to complete many exciting kits.  (Batteries Sold separately)

*** Please Note:  The PK-Series kits do not require solder and are built using a Solderless prototype board. If you are interested in Solder kits please check out our SK-Series for our Solder kits.***
