if you would have read the original post, you would know that each of the pieces would have a cheap 1.5 $ power banks that have a lithium battery and a small circuit board that comes with them. these provide power the second any load i applied on the USB. my plan is to have the circuit on the usb in series with a switch, and the micro usb extended to the back for charging. i need PWM or any method that would allow dimming of the LEDs. for the effect of the LEDs becoming dimmer and brighter as they fade in and out. just for visual purposes to make the gift look more appealing
Welcome to life as it exists on a Forum (grin). If you're not reasonably knowledgeable in the subject you're asking questions about, you're not going to be able to filter the responses you get or you may not recognize a viable solution when you see it.
Sorry, Ernie... That question was directed at Spinnaker's rather broad unqualified statement..
I happen own that thing. It was quite a useful tool back in the 90's when I got it.

;Date: 1.14.03
;Version: 1.00 (8 LED Version)
;Description: This is a C written program designed to show the user
; an interrupt driven LED State Machine.
; Also, the program shows an interrupt on pin change to change the
; speed at which the leds are flashing.
;
; This program uses the intlib.obj library file. The library
; contains the led display & push button debounce functions The
; source code for the library can be found in the intlib.c file

;How To Flash LED's
;****************************************************************************
;To Flash LED's simply write the 8-bit value into the variable ledregister
;in main()
;
;i.e. ledregister = 0xFF Flash 8 LED's D7-D0 (D7 is most significant bit)
; (D0 is least significant bit)
;To Change The rate at which the LED's flash push button SW1

}No need to be an ass about it. Twice
Do they even make the 1 anymore? I think the 2 can still be bought but does not support the latest chips. But the two is really nice for someone starting out as it has a logic analyzer that would be nice to play with.
Read my post again. I was not referring to you. It just happened to land under your post but was quoted. Nothing wrong with your post IMHO.
I feel sorry for you...
