Programming LEDs individually

[dblackard59]

I want to turn on 1 or 2 LEDs at a time very slowly. Is that possible?
If yes, please recommend the best PC software to do that.
Thanks for any help.

Possible? Yes!
I don't know about a PC software. Usually it's done by a microcontroller, e.g. an Arduino.
Either by using PWM or by using adressable LEDs (e.g. WS2812B).
Heaps of tutorials on either of these techniques is available on the internet. Would you be comfortable with programming an Arduino?

You don't need software. Just use two LEDs and two switches.

Turn one on today, turn the other on tomorrow. Slow enough?

Slow enough?

My understanding is the op wants a fading effect, not a delay in on/off of the LEDs. Would you agree?

Thanks for your help. I have worked with Arduino. I will investigate.

You’re on fire today!.

Here is a simple programmable timer application you might consider :

Pulse Sequence Generator / Smart Timer

Often users, developers, hobbyists need timed and qualified event generators, many resorting to 555 timers and the like. The venerable 555 has had a long run but its limited in accuracy and capability. This approach uses block language to create...

High power LEDs ?

You can do this task with an Arduino and 2 LEDs. You will need to connect the two LEDs with 2 PWM pins.
