Hello, I am currently taking ECE 1, which is the first year electrical and computer engineering course.(I am a freshman) For our project, we have to build and run our cirucit of our choice. The circuit we decided to make was a infrared receiver and transmitter. Everything works great on it. Now, I need to describe how the circuits work. Since ECE 1 is a first year engineering class I don't have to get too technical but I need help explaining it to my class. This is where we obtained the kit: http://www.rainbowkits.com/kits/ir-2p.html
Here is the schematic for the transmitter:
And here is the schematic for the receiver:
I made these schematics in multisim. The transmitter works, but I couldn't find the MP3372P (Remote control amp and dector) so i tried making a custom component in multisim for it. It doesn't function but I mainly did it just for the layout. I understand that the photo pin diode converts light into voltage, the basics on the IR led, and the basic functionality of the capacitors and resistors but I can't piece everything together in order to see how it functions. Can anyone give me some insight on these circuits? Does anyone have suggestions for some readings? I really appreciate it. Thanks for your time.
Thanks,
Matt
