I need a schematic design to create a bina all information will be passed to a microcontroller. Requirements: - all items have here in Brazil - Identify calls, and inform the microcontroller - Identify phone ringing, and enter the number on the microcontroller - identify phone off the hook, and inform the microcontroller. - Have input and output from rj11 - Have the possibility to connect a plug p2, for external control. Conclusion This design is just one more accessory module for microcontroller power. Because there are several other modules that will work together. In the budget present components that will be used. For some prototypes have already been performed without effectiveness.
