April Fools’ Arduino alarm

April Fools’ Arduino alarm

After we put the kids to bed last night my wife and I realized we needed to set up some April Fools’ Day pranks. So I built this motion sensing alarm and tucked it into the shampoo bottle recess in the shower. When the kids entered the bathroom they got an earful of beeping piezo buzzer for their troubles!

With the LED Clock Kit, you create a giant 9″ x 5″ super bright self-standing clock only 1/8″ thick that keeps accurate time even during power failures up to 1 minute.

Your finished clock will change brightness at the push of a button, the digits fade smoothly when the time changes, and you can automatically synchronize multiple clocks.

This kit is easy to assemble & no soldering required. The unique wiring pattern doesn’t need a traditional PCB with tiny parallel tracks on it. Simply twist the LED leads directly to other leads. Only six conductors enter the panel.
