SUMMARY

The discussion focuses on transmitting a single byte (1010 1010) over infrared (IR) to an RS 232 port. Key components identified for this task include an IR photodiode and a phototransistor, which are essential for the signal transmission. The user also mentions utilizing a shift register to prepare the data for sending. This setup is crucial for establishing a reliable communication link between the IR transmitter and the RS 232 interface.

PREREQUISITES
  • Understanding of RS 232 communication protocols
  • Knowledge of infrared transmission technology
  • Familiarity with shift registers and their operation
  • Basic electronics concepts, including photodiodes and phototransistors
NEXT STEPS
  • Research circuit design for infrared communication systems
  • Learn about RS 232 signal levels and timing requirements
  • Explore the operation and configuration of shift registers
  • Investigate the characteristics and selection of IR photodiodes and phototransistors
USEFUL FOR

Electronics hobbyists, engineers working on communication systems, and anyone interested in infrared data transmission techniques.

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

:. sorry double posting

Before anyone gives Tko grief about double-posting, it was my suggestion that (s)he resubmit this here after I ran across it in General Physics. This seems to be a more appropriate location.
