  • 2x 7-segment displays multiplexed using a potentiometer as the input for values.
    As the pot is turned the value displayed on the 7-segments is increased to display the current numerical value. This is the base system for a future volume control system that has a value of current system volume displayed, and controllable through the potentiometer or the computer.

    Basically the circuit has 8x 220Ohm resistors wired directly to digital pins 2-9, from there 2 jumpers per resistor are wired to the specified pins on the 7-segments. To achieve the multiplexing the grounds for both displays run to there own circuits containing an NPN transistor and a 1000Ohm resistor, digital pin 11 and 12 are wired to the Base leg, the ground running from the displays is wired to the collector leg, and the Emitter leg is wired to a common ground on the arduino. This circuit allows the display grounds to be pivoted so control of which displays output can be set. In addition to those, the potentiometer has a +5v running into one of the outer legs, the other outer leg is wired to a common ground, and the center leg is wired to analog pin 0 on the arduino.

    The displays I used are technically 8-segment displays including the decimal place, serial numbers on these specific displays are “MAN74A 432 D”.

    Edit: Here is the C code to the circuit, its fairly simple gets the job done with the essentials. http://pastebin.com/8q0EyQvk Feel free to email me or PM me for any questions or if you want any clarity or such.

    Here is an image to the schematic http://img33.imageshack.us/img33/3431/7segmentmultiplexed.jpg
    (sorry there are no labels on the resistors, I would say 220 Ohms or so would work fine for the 7-segments and 100 Ohm or so for the transistors.)

    An advanced and fancy looking 7-segment display! Go ahead and use this for anything you’d like :)

    - 10 different inputs (0-9)
    - Bud-switch powered
    - Extremely compact
    - Fast
    - Easy to get outputs :)

    In China, we have purchased many times, this time is the most successful and most satisfactory, a sincere and realiable Chinese manufacturer!
