I am working on a small circuit where an LED will activate a photodiode that controls a series of gun, blaster and explosion noises. I am thinking of the 8 sounds that were popular in cheap toy guns.
Heres a youtube video of the sounds I am looking for: YouTube - Executor 8 Sound Keychain
The project is to add some sound to a roomba. Inside of the roomba there is a piezo sensor that us used to detect high concentrations of dirt. When the sensor is set off, an LED indicator turns on and the roomba drives in small circles in an attempt to better clean the area. When that LED is on I want to hear blaster noises.
There used to exist an IC by Holtek, the HT2884, that made all of these sounds. I am having a hard time finding a supplier. The manufacturer doesn't even list it on their website so I have little hope.
I did find a COB module here: **broken link removed**
They are less than $1 a piece. I don't know for sure, but the documentation makes it look like there are 8 switches, one for each sound. I would really like to be able to have just one pin that cycles through the 8 sounds. I could use a counter IC but I am trying to use the least amount of PCB area for this project as possible.
If anybody could suggest an obtainable IC for this project I would appreciate it.
Thanks
