WebTo test it, connect a 5V power supply to your breadboard, and connect the ground wire to the pin 1 connection. 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.

The formula is: N = n² - n, where n is the number of pins, and N is the number of LEDs they can drive. Charlieplexing can multiplex far more LEDs than traditional R/C multiplexing, but is harder to program for and wire up. So concretely (to answer precisely OP), 5 pins (3 ...

http://www.fringeneering.com/2012/10/multiplexing-vs-charlieplexing.html Display multiplexing is very different from multiplexing used in data transmission, although it has the same basic principles. In display multiplexing, the data lines of the displays* are connected in parallel to a common databus on the microcontroller. Then, the displays are turned on and addressed individually. This allows use of fewer I/O pins than it would normally take to drive the sam…

WebCharlieplexing is a technique proposed in early 1995 by Charlie Allen at Maxim Integrated Products for driving a multiplexed display in which relatively few I/O pins on a microcontroller are used to drive an array of LEDs.The method utilizes the tri-state logic capabilities of microcontrollers in order to gain efficiency over traditional multiplexing. WebAug 7, 2012 · Aug 7, 2012 at 20:07. Add a comment. 5. What you describe is a 2-to-1 multiplexer, like the 74HC157, which is a quad 2-input multiplexer, so 2 inputs to 1 output, and 1 select input. You use two multiplexers for the four inputs. The 74HC153 does a similar thing, but it's a dual 4-to-1 multiplexer, so 4 inputs, 1 output and 2 select lines per ...

WebMay 6, 2024 · The Wikipedia article on Charlieplexing says that you CAN turn on more than one LED at a time if they have a Common Anode. Set the common anode pin HIGH and set the two cathode pins LOW. I think the Common Cathode configuration would also work. Set the common cathode pins LOW and set the two anode pins HIGH.
