kit problems

by datzekt on Thu Feb 02, 2017 2:36 pm

i have buy a xox-kit with v1.01 platine
in the manual R201-R234 and R237-R270 ar 10K-resistors. in the kit was 33 pcs of 10K and 40 pcs of 1K resistors.
i changed the 100Ks to 10K and soldered. but all is not going ( no leds, no sound). all tests before was ok. now i opened a other (this xox is working) xoxbox with v1.0 platine. there are 0,3K inside (R237-270).
what is wrong, what is right?

the 40 resistors are means as current limiters for the LEDs.
the value depends on the type of LEDs you are using.
check which value you prefer, but normally 10k is fine-ish with normal red diffuse leds. Make sure it is visible both in darkness and daylight, and doesn't "burn" your sight.
