Dear All,
I am new to DTMF as well as to this group so forgive me in case of "stupid" questions...
I am looking for hardware to control 16 solenoids using DTMF tones. In fact I am building an instrument consisting of 16 automated castagnettes.
My goal is to find a solution as simple as possible to drive the castagnettes.
My basic idea is:
1) Use a MP3 player to store a "song" consisting out of differtent DTMF tones
2) Use a simple DTMF receiver connected to the MP3 player to detect the DTMF tones (e.g. MT8870D / MT8870D-1 Integrated DTMF receiver)
3) Use simple electronics connected to the DTMF receiver to drive 16 solenoids. (Solenoids: 12VAC or 12VDC)
Does anyone of you know a simple approach to do this? I know just enough about electronics to build a simple schematic.
I really hope anyone of you can give me some help!
Best regards, Eibert Draisma.
