In this example I will be using 2 x and 2 x 7 segment module. Leave a reply Click here to cancel the reply Your email address will not be published. Using the 7 segments, you can make any decimal digit. Your email address will not be published. For normal operation, Latch Enable LE datasgeet held high, but when it is grounded, the takes the 4 line input and updates its internal registers. Already have an account? This provides a little over 5ma for each segment.

The pin-out for the is shown below, and the datasheet is available at here. Each IC datsaheet a binary number as an input, then outputs the necessary lines to display that number on the 7 segment display. Once you do this the number will be updated on the 2 LED modules.

Since this is being powered by a 9V battery, I am using 1.

This connection is available on pins 3 and 8. Now we will build a very simple circuit to drive a single digit. Go to the shop. Next article Severed hand in a jar Halloween display.

This calculator will help you figure out the resistor size http: The segments are then displayed on the basis of those internal registers. We are factory specialized in making LED 7-segment display, dot-matrix display, light bar display and abnormity digital display. Datasyeet trying to drive a single 7 segment display but i dont know how.

This means that the negative side of all the LEDs are connected together. If the voltage is too high or the resistor too low think of the wire being a resistorthe current going through the LED will exceed the maximum forward current and burn out the Cd4551.

Driving a 7 segment display with a 4511 BCD to 7 Segment Driver

The modules we will be using have a common cathode. 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. I used the LED resistor calculator on ohmslawcalculator. First we need to familiarize ourselves with the 7 segment module.

We will use a DIP switch to turn various segments on and off. In this tutorial we will show you how to setup an AVR Eclipse development environment Remember Me Lost your password?

The ATmega has See the example below. Those are symbol for LED, to represent the 7-segment display, not normal diodes.

The photo below shows the finished circuit. This is just for information. Each segment is identified by a letter as can be seen below as well as the pinout and schematic for reference.

Every LED has a maximum forward current and forward voltage. Now controlling a 7 segment display like this is OK, but we can do much better.
