Remote Control Receiver Using IR with RS232 Output

The circuit was constructed to produce a remote control by utilizing infrared technology and providing the output through the RS232 interface.

The ATtiny2313 microcontroller used in the circuit is where the object file is being written to. It is a low power COMOS 8-bit chip that is based on the AVR enhanced RISC architecture. It provides throughputs that are almost 1 MIPS per MHz by executing powerful instructions in a single clock cycle. This allows the designer of the system to optimization in power consumption against the processing speed. It was manufactured using high density non-volatile memory technology of Atmel and its AVR is supported with a full suite of program and system development tools.

During the operation of the circuit, the data received by the infrared is being converted on American Standard Code for Information Interchange (ASCII) characters which represent text in computers, communications equipment, and other devices that function with text. The data will then be sent through the output port of RS232 which is commonly used in computer serial ports as a standard for serial binary data signals. RS232 is simple, well-understood, and a universal data interface.
