I'm making a giant score board made out of LED strips, for our rugby club. it has 4, 7-segment displays, with every segment made out of a peice of LED strip, drawing 300ma on 12V. The arduino is connected to 2 SAA1064 chips by i2c. The SAA1064 is a dual 7segement controller. However, it is a current-sink IC. As every segment pulls 300ma, there has to be a transistor between the segment and the IC. Can someone point me to a transistor that can switch this load, and with matching resistors? I'm not that good with electronics so a little help would be awesome.
I've found these pnp transistors, is this the right way to go?
