Halloween is coming up and it’s time to do some pranks.
Everyone likes Halloween and I’m no exception. Every year me and my wife decorate the house with lot’s of bugs, spider webs, creepy posters and of course lot’s of Halloween candy.
While making the normal Halloween preparations I came up with the idea of making a circuit that would make some scary noises and also would react to movement.
I expect to get some screams and laughs from friends that come to visit us this year.
The circuit is basically a sound chip that records and stores sounds in memory and plays them back with a microcontroller and it’s triggered by light and motion.
The sound chip is from maker winbond and has a very good sound quality.
