Hi, I am making an interactive led table using ir sensors and emitters and 360 leds. Each pixel is 4 " x 4 " square, with a 3 x 3 led setup in each. There are a total of 8 x 5 = 40 pixels in the table. In this youtube video........ http://www.youtube.com/watch?v=K4HRXa-GxIk&feature=related ... he says that he only uses 1 led driver for all of those leds, how is that possible? I thought, for instance with the tlc5940, only 16 leds could be driven? Am I wrong? I do NOT want to have to buy 40 TLC's for this project, please let me know.
