hie, my project involves an audio milivoltmeter attached to a chair and when the person in the chair talks or makes noise the audio milivoltmeter detects the nois, measures it and then transmits the readings via infrared transmission to a CPU or terminal where the readings are displayed.
Now the problem is, im not sure how to go about building the infrared transmission system and also the decoding needed by the system. Any solutions , diagrams or schematics are very much appreciated. Thank you.
