The green LED did nothing when I got to the test step.
I continued anyway and finished the board.
I went over my soldering and to my eyes at least it all seems to be OK.
I cleaned between the traces just to make sure.
I used both rechargeable batteries and then fresh alkaline batteries.
Could the chip be bad? Is there a way to test it?
Thanks.
Can you help please?

Re: Green LED does not flash
if you build a kit and it does not work half-way, do not continue. it will not magically fix itself, and it can be harder to repair

Re: Green LED does not flash
resolder all your components
we see many of them are not soldered completely

I redid all of the joints with the same result. Nada.

Re: Green LED does not flash
Is the IC in the socket around the right way? Are any pins bent up underneath instead of in the socket?

Re: Green LED does not flash
I IC socket is in the correct way and no pins on the chip are bent.
I got a new chip in the mail today and it still does not function at all.
No green blinking green LED when batteries are inserted or when button is pressed.
Please advise.
Thanks

Re: Green LED does not flash

Re: Green LED does not flash
I agree that something else is wrong.
I was pretty careful during assembly following instructions.
You can even see from the photos that the LED orientation is correct.
Do you have any other ideas?

Re: Green LED does not flash
hmm, check all the components, are they they the right type? the 2 transistor types look very similar

Re: Green LED does not flash
Q1-Q4 are all labeled:
PN
2222A
A28
Q5 is labeled:
PN
2907A
A13
I think that's correct according to the parts list.

Re: Green LED does not flash
it might be the crystal, which hasnt happened but we're not sure what else it could be, sorry. you can email support@adafruit to get a new kit.
