Building a fun project SONY TV remote with timed MUTE keys.
Using new original UNO board( yes. Pin 3 and IR lib included)
Code loads and works fine.
When using any regular LED, the LED works fine
But when testing with IR LED and using live video from phone, its not firing.
When removing the resistor, I see a very wimpy firing.
Purchased a replacement batch of IR LEDs with no change. Then got a working SONY remote and substituted that IR LED. No change. (Yes- all polarity is correct)
Then I added a N222 transistor with an additional 5V. Still no change!
I saw comments on; https://forum.arduino.cc/index.php?topic=379459.0 but that is not helpful.
It seems as if the IR LED is not getting enough power to correctly fire.[/i]
I’ve spent the entire quarantine lock down trying to get this 15 min project to work.
