First we need to familiarize ourselves with the 7 segment module. Using the 7 segments, you can make any decimal digit. The modules we will be using have a common cathode. This means that the negative side of all the LEDs are connected together. This connection is available on pins 3 and 8.

Each segment is identified ccd4551 a letter as can be seen below as well as the pinout and schematic for reference. Now we will build a very simple circuit to drive a single digit. We will use a DIP switch to turn various segments on and off. Since this is being powered by a 9V battery, I am using 1.

This provides a little over 5ma for each segment. I used the LED resistor calculator on ohmslawcalculator. See the example below. Now controlling a 7 segment display like this is OK, but we can do much better.

Each IC takes a binary number as an input, then outputs the necessary lines to display that number on the 7 segment display. For normal operation, Latch Enable LE is held high, but when it is grounded, the takes the 4 line input and updates its cd4551 registers. The segments are then displayed on the basis of those internal registers.

Cd45551 pin-out for the is shown below, and the datasheet is available at here. In this example I will be using 2 x and 2 x 7 segment module. The photo below shows the finished circuit. Once you do this the number will be updated on the 2 LED modules. The ATmega has We are factory specialized in making LED 7-segment display, dot-matrix display, light bar display and abnormity digital display.

Those are symbol for LED, to represent the 7-segment display, not normal diodes.

This is just for information. Im trying to drive a single 7 segment display but i dont know how. Every LED has a maximum forward current and forward voltage. If the voltage is too high or the resistor too low think of the vatasheet being a resistorthe current going through the LED will exceed the maximum forward current and burn out the LED.

What you need to do is select the appriate size resistor which will ensure you still have decent current goiing through the LED without burning it out. This calculator will help you figure out the resistor size http: Your email address will not be published. Cd45551 article Severed hand in a jar Halloween display.
