I used the LED resistor calculator on ohmslawcalculator. In this example I will be using 2 x and 2 x 7 segment module. The segments are then displayed on the basis of those internal registers.

Now controlling a 7 segment display like this is OK, but we can do much better. 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. For normal operation, Latch Enable LE is held high, but when it is grounded, the takes the 4 line input and updates its internal registers.

First we need to familiarize ourselves with the 7 segment module. Each segment is identified by a letter as can be seen below as well as the pinout and schematic for reference. The pin-out for the is shown below, and the datasheet is available at here.

Using the 7 segments, you can make any decimal digit. The photo below shows the finished circuit. Remember Me Lost your password? The modules we will be using have a common cathode. Once you do this the number will be updated on the 2 LED modules.

See the example below. We will use a DIP switch to turn various segments on and off.

Im trying to drive a single 7 segment display but i dont know how. A few hacks to make bread boarding easier 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. This is just for information. Next article Severed hand in a jar Halloween display. Leave a reply Click here to cancel the reply Your email address will not be published. Every LED has a maximum forward current and forward voltage.

Hacking the power buses The power Since this is being powered by a 9V battery, I am using 1. We are factory specialized in making LED 7-segment display, dot-matrix display, light bar display and abnormity digital display. This calculator will help you figure out the resistor size http: This means that the dtaasheet side of 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. Those are symbol for LED, to represent the 7-segment display, not normal diodes. This connection is available on pins 3 and 8. Your shopping bag is empty.
