Most of the newbies are confused about using two or more seven segment displays, here is an instructable showing the implementation of the same with a microcontroller.
Learn how to set up and program seven segment displays on an Arduino. We'll also see how to display temperature readings from a thermistor.
In this tutorial we will show you how to use the 2-Digit seven segment display with the Arduino UNO board. We will use the countUP () and countDown () functions to count from 0 to 'number' (variable) and from 'number' to 0.
Multiple digit displays (multiplexing) The circuit in figure 6 shows an Arduino SBC connected to two seven segment displays. Note that only two additional I/O pins are used to drive the displays. They are used to turn each display on and off. Both displays share the same segment pins but only one display is on at a time. Multiplexing the displays like this enables you to use one set of segment ...
