Then touch the 5v power to pin 2,3,4,5 in turn. For every wire one (and only one) LED should light up. If 2 LED's light up for every single wire, make your resistors bigger by about 25% and try again.

WebThis unusual multiplex technique is used by the MAX6950, MAX6951, MAX6954, MAX6955, MAX6958, and MAX6959 LED display drivers. Charlieplexing reduces driver pin-count by using some pins alternately as cathode and anode drivers. This differs from the standard LED multiplex connection, which uses separate driver pins for anodes and cathodes.
