I have a website that contains a large number of members. I need a website/member based Instant Messaging system that will include:
(1) audio/video chat.
(2) I have an analog device that outputs a voltage swing of 2.5 - 4.0 volts at a frequency of 0 - 5 hertz. The output signal while at 2.5 volts would represent the device's quiescent (minimum) state. The output signal while at 4.0 volts would represent the device's maximum state.
I need a USB based embedded solution that will power and interface this analog device to the web based Instant Messaging system. In effect creating a real time data acquisition system that would graphically display these voltage swings on a line graph chart that would be featured somewhere within the window of the web-based Instant Messaging system.
For example, members would see the current temperature of the other member's location printed in real time on a line graph chart.
