Hi. I've been working on this since our project was given and i could find help from any one else.
I need to build a circuit that can amplify a mic, modulated in PWM, transmit through infrared then receive, and demodulate.
This is so far what my knowledge knows:
**broken link removed**
And this is my schematic:
**broken link removed**
I know there are still a lot of bugs in this design. I really don't know how to design circuits myself.
Comments, suggestions, criticisms are welcome. Thanks.
PS: IR LED & photo-transistor are just labels. not wired.
