tko_gx said:does anyone know how what type of circuit i need to transmit a signal over InfraRed. the signal i want to transmit is for example one byte -> 1010 1010
the byte sent will be sent to a RS 232 port
i have a shift register with the data ready to be sent
i know that i need a IR photodiode and a phototransistor
An InfraRed (IR) Signal is an electromagnetic wave with a wavelength longer than that of visible light, but shorter than radio waves. It is commonly used for remote controls, communication between devices, and data transfer.
In order to send an IR signal to RS 232, you will need an IR transmitter and an RS 232 converter. The IR transmitter converts the digital signal into an IR signal, which is then received by the converter and converted back into a digital signal that can be understood by the RS 232 device.
The circuit requirements for sending InfraRed Signal to RS 232 include an IR transmitter and an RS 232 converter, as well as a power source, appropriate wiring, and proper connections between the devices. The specific circuit requirements may vary depending on the specific devices being used.
No, not all devices can be used as an IR transmitter for sending InfraRed Signal to RS 232. It is important to use a device that is specifically designed for this purpose, as it will ensure proper functionality and compatibility with the RS 232 device.
No, a converter is essential for sending InfraRed Signal to RS 232. The converter is responsible for converting the IR signal back into a digital signal that can be understood by the RS 232 device. Without a converter, the RS 232 device will not be able to receive and interpret the IR signal.
