Pulsing an infra-red Led transmitter

[jen12]

How to pulse an infra-red LED transmitter using a PWM? if not possible, is there any other way to do so?
(I'm using Arduino-uno)

You didn't like/understand the triangle idea?

I did like it ,but I am trying to find as many ideas as possible to try them all.

Pulsing is hardly difficult - turn it ON, wait a bit, turn it OFF, wait a bit - repeat.

You could obviously use PWM to do it if you wanted as well, as long as you can adjust the frequencies.

However, presumably the transmitters aren't connected to the Uno, and the Uno is trying to detect them?.

In which case you could use 555's to pulse them.

Thank you so much. I appreciate it.
