Now controlling a 7 segment display like this is OK, but we can do much better. Remember Me Lost your password?

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

Every LED has a maximum forward current and forward voltage. In this example I will be using 2 x and 2 x 7 segment module. We will use a DIP switch to turn various segments on and off.

This is just for information. Im trying to drive a single 7 segment display but i dont know how. Now we will build a very simple circuit to drive a single digit.

Those are symbol for LED, to represent the 7-segment display, not normal diodes. The modules we will be using have a common cathode.

This provides a little over 5ma for each segment. The segments are then displayed on the basis of those internal registers. This connection is available on pins 3 and 8.

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 LED.

Each segment is identified by a letter as can be seen below as well as the pinout and schematic for reference. I used the LED resistor calculator on ohmslawcalculator. The pin-out for the is shown below, and the datasheet is available at here.

This calculator datashedt help you figure out the resistor size http: Your email address will not be published. Using the 7 segments, you can make any decimal digit. Since this is being powered by a 9V battery, I am using 1. See the example below. We are factory specialized in making LED dafasheet display, dot-matrix display, light bar display and abnormity digital display.

Once you do this the number will be updated on the 2 LED modules.

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. The photo below shows the finished circuit. Leave fatasheet reply Click here to cancel the reply Your email address will not be published.

This means that the negative side datasheer all the LEDs are connected together. Each IC takes a binary number as an input, then outputs the necessary lines to display that number on the 7 segment display. A few hacks to make bread boarding easier First we need to familiarize ourselves with the 7 segment module.
