Carrier duty cycle issues for JVC devices #1191
-
Hello, I have an L336 learning remote control and a partially defective JVC remote control. I was able to read almost all button codes using the Arduino program “ReceiveDemo”. |

unlikely related to duty cycle.....maybe post your IR send circuit |

you are getting less than 20mA current thru the IR LED. Try changing R3 from 180R to 22R or 10R or the closest you have. Also make sure you place the emitter as close as possible to the learning remote when capturing.. |

The output is generated with a 30% duty cycle .
How do you manage to get a 50% one?
