Hello everyone. Fairly new to electronics and stumbled on to this site on accident. I'm currently working on a throbbing led which fades on to off in about 5 seconds.
I'm using a 555 timer with a resistor between 555 and NPN (for pulse time)and a cap for fade time. I think that's what each component does. I was sent the schematic to try it out.
I have a working fade on my breadboard but was wondering if it was possible to alternate another led. Ex. fade up/down blue, fade up/down pink, repeat.
Looking for a slow 5ish second fade between leds.
Once I get it completed, I want to etch some pcbs and put them in some frosted vases for an upcoming wedding.
Sorry for my ignorance.
Thanks for any input. I'll try to edit in schematic when I get back to my normal computer.
Dumb question but isn't this a version of PWM with a set cycle?
