Abstract
Today most of household appliance such as TV and refrigerator can be controlled remotely. So the study in remote controller became more and more important recently. The main research on remote control technique are mostly about blue tooth ,wireless, voice control and infrared control. This tutorial paper use the infrared control which is the most popular now.
In this paper ,there are two aspects on the research in detail. First ,I design the transmit chip include generating key codes and remote control codes , modulating the codes and transmitting . Than we study how to receive the codes including amplifying the codes , filter , detecting and shaping. On the basis of the study we mentioned above, I design the decoding program using in receiving remote codes.
On the basis of theory I studied , I designed the transmitting chip and receiving chip using in remote control and simulated it in order to make sure that the codes are received correctly.
