Is it possible to control straight away 5-digit 7-segment LED display with Arduino. There's a good section describing why the display gets dimmer as more digits are used. A circuit which would be able to power up 4 pieces of 4 inch 7 segment LED display, and with the help of multiplexing I will employ my arduino to lit it up to display desired numbers. And multiplexed by control signals which means the 7-Segment display units are not going to be working together all the time. I notice that you only have one resistor limiting the current for each display. Using the 7219 we can control up to 8 seven segment displays while using only 3 pins from the Arduino. The simplest way to drive Seven Segment Display is by using a driver or decoder and are available for up to 4 displays. To write a 4 digit number, you'd first pull all the grounds high to disable the displays. Now I have made the mistake, so that when calling the showDigit () function, although the correct numbers are displayed, but not on the mentioned digit from the parameters. The display can be used in both direction. when it says they´re HIGH they´re off an when it says they´re LOW they´re on. Multiplexing, in a nutshell, means doing one task for a short period of time. So, no need to include multiplexing code for a multi-digit display. Arduino 7 seg display is used in a different application like a digital counter .
