Description

Arduino Serial Communication Over Infrared


In this scheme, I would like to demonstrate how to perform the Serial communication over infrared photodiodes. So, I set up a simple scheme where it only uses photodiodes plus some resistors, and in this case, I chose not to use TSOP (to make it simple) once this works with a frequency of 38khz, and for that, would be necessary to build a carrier on the transmitter side. Soon I will show you how to make a similar circuit using TSOP, which makes it a more reliable communication.

Parts:
2x Arduino Uno
Photodiode TIL 32
Photodiode TIL 78
Resistor 220 Omh
Resistor 330 Omh
Resistor 1k Omh

Amazing project. You used same pc to transmit datas. Can I use two pc ( one on transmitter side and other on reciever ) with this same layout and code?

  Are you sure? yes | no
