DIY KIT 63- Multi-Functional Simple Electronic Password Lock Circuit

I found this small kit on Ebay. The kit is pretty easy to assemble. The following video shows the assembly steps. The kit actually turns on the LED when you press switches, 1, 4, 7, and 9. That’s it.

Check out all the assembly steps below. You can see the images on Flickr also.
