Please look at the attached circuit and see if you can find anything wrong. The first LED's 1-17 should sequence followed by LED's 18-22 with each one fading off in about 3 seconds, and then starting over after LED 22 fades off. I have breadboarded this, but only hooked up Led,s #18 &19 circuit, so, I hooked up pin 15 (res) of IC2 to pin 7 of IC4. The first 9 do not light and 10-17 only light and sequence when I touch the metal base on my breadboard (crazy huh). I have checked the wiring and have swapped out IC's to no effect.

 

Don't know what app reads that file type. Can you post it as a more common image file, like a PNG?

 

When I click on the above attached file, it brings the schmatic up. When posting a new thread, below in the attachment list, it has sch. as one of the approved forms, so I don't know why it won't come up for you. I'll try another file.

 

.sch is an approved format so you can share it with those who use the same program as you.

You need to do a print screen, open paint, paste then save as .png format. Then all can see what you want us to see.
