This is the electronic equivalent of a mechanical music box. It is light activated and plays a range of tunes.
It is activated by light falling on the light dependent resistor (LDR) sensor. The kit can be placed anywhere that you want a tune to play when light falls on it.
You can make a cupboard music box or fit it into children's toys or promotional products. Alternatively you could replace the LDR with a conventional switch.
It is supplied with two different music ICs; the M3481 contains eight Christmas songs (Jingle Bells, Santa Claus Is Coming To Town, Silent Night,Holy Night, Joy To The World, Rudolph The Red-nosed Reindeer, We Wish You A Merry Christmas , O Come All Ye Faithful, Hark The Herald Angels Sing) and M3485 contains five tunes (Hawaiian Wedding Song, Try to Remember, Aloha OE, Love Story & Yesterday).
The board has a jumper to select playback of One/All Tunes and another for Autostop. An onboard switch provides manual tune selection.
All components, PCB, speaker and 2 x AA battery holder included (battery Order Code 656.010). Provides a good introduction to a variety of electronic components and technologies.Specifications
