ouch price is expensive ! I saw some projects using shift register 74HC595 to their score board (also with 12v leds). Can you help me to use this shift register (74HC595) with my leds 12v ??
Before to use Ir remote, actually I got USB cable to power my arduino (5v) also my shift register.
And I got a power supply (12v) for my leds. I wonder, why I could have not only 1 power : both for my arduino and leds ??
What do you think about TPIC6B595 ? Someone said "he's big brother of 74HC595". It can replace both tip120 and 74HC595 ?
Thanks you! I never plugged power jack (12v) because I was afraid to fry my Arduino lol

I've never used a TPIC6B595, but from the datasheet I see that each output can source up to 150mA continuous
If you connect anything more than a few TPIC6B595s to the 5 V however, it will likely overheat and shut down intermittently. It would be better to use one of the switchmode "buck" regulators readily available to feed proper 5 V to the Arduino via its 5 V terminal.
See reply #11. Given you are using only two of the three LED sections which will draw just 120 mA for each segment, the TPIC6B595 is the perfect solution.Rubbish!
So, does "Rubbish" refer to this?
