Hi.
I am looking for some simple schematics and help building an Infrared-Receiver and audio amplifier.
I want to build a really simple infrared receiver that will turn on a circuit or flicker on a led from a few meters away in response to infrared light from a remote. I have a voltage regulator (276-1770A) and an Infrared Phototransistor (276-145A).
The second circuit i am trying to build is an audio amplifier. I want to build a simple circuit that will allow me to do the similar things as I explained in the infrared receiver. But instead I want to use a condenser microphone or similar type speaker to have an led react to sound. But I need to find a way to amplify it to make it more sensitive.
thanks for any help you guys can give.
