Can anyone tell me how to wire this kit for battery use? (Please don't say read the PDF data sheet. Trust me, I have.) I would like to use 3 AAA batteries.
Heres what I've got right now, and it isn't working: The positive lead is on X2, the negative on the other DC input hole.
Regulator is bypassed with a wire jumping the two outside holes together, the middle is left untouched.
Also, I removed the LED because I was unsure of polarity and simply bridged it with a wire.
Anything wrong with that? Why might it not be working?
the chip needs 5V to operate !! No oneder yours isnt working if youa re only using 3 batteries there just aint enough voltage
The specs for the chip suggest "2.4V to 5.5V operating voltage".?
That's why I was concentrating on reverse polarity, accidental short or open circuit rather than on the < 5V supplied.?
Since it's a kit, you've also got to wonder whether it was constructed correctly. Did it (for example) work correctly from (say) 9V before the modifications were commenced?
