Very Small Information Systems/SS2006/Creating a microphone for JOP
This is a decription on how to make a microphone module for the JOP Board
The objective with this article is to descibe how to make a simple analog to digital converter using the Sigma Delta converter model: Sigma-Delta ADC Tutorial
Following components are needed to make the hardware part of the analog to digital converter:
- A microphone
- Two resistors- one 100K and one 1M
- Two capacitors one 220 nF and one 47 pF
- One Printed Wiring Board(PWB) to assemble it all on
The circuit diagram
editSolder it all together and attach it to your JOP board, then you should end up with a result that looks like this.
