Powering Foot Tall 7 Segment Display
this may dumb question, can arduino uno power 12 inch tall 7 segment display? here data sheet display , product page: http://evilmadscience.com/productsmenu/partsmenu/107-sevensegment & http://s3.amazonaws.com/evilmadscience/im/led/bl-se1200a.pdf.
thanks in advance

no, arduino outputs can handle 5v @ 40 ma, near 31.5v @ 80 ma.
the model stock common anode means segments share common + side , have separate - sides. need + side driver can handle 35v @ 560 ma (80 * 7) , - side drivers can handle 35v @ 80 ma (like npn transistor or n-channel mosfet). power 35 40v @ 560 * digits ma (more half , amp per digit).
