6 Types Of Segment Displays

-

Introduction to segment displays: Segment displays are electronic devices that present information through segmented digits or characters. Comprising individual illuminated segments, they commonly showcase numeric or alphanumeric information. Widely used in digital clocks, calculators, and electronic signage, these displays provide clear and concise visual representation of data.



Types of Segment Display

1. 7-Segment Display

This is a 13 mm single character 0.56 inch 7-segment common cathode display. It is designed such that all the anode pins of the LED are connected to Vcc. The viewing distance can be up to 7m and the display color is red. The drive IC has to sink enough current through it to glow the respective LED. Seven segment Display is commonly used along with microcontrollers or display drivers in applications where a bigger and a brighter display are needed. Alternative to this, is the 7-segment common cathode display.

2. 4-Digit Seven Segment Led Display Module

This 7 segment LED Display has 4 digits which are controlled by TM1637 Driver Chip. It requires only two connections to control this TM1637 4 Bits Digital Tube LED Display Module. Also thanks to the I2C Bus you can control it using only 2 wires, leaving more pins available on your Microcontroller to connect other things.

The module is a 12-foot clock with four common anode tube (0.36 inch) display module for driver IC TM1637, only two signal lines can make the MCU control four 7-segment digital tubes. 

3. 10 Segment LED Bar Graph

In many of our day to day applications we need to know the approximate amount of content left in the store. Wouldn’t it be great if we know the amount of juice left in a carton or amount of breads left in a box? Just kidding! But in electronics we use these 10 segment light bar to determine the amount of battery charge left, the amount of liquid resin left in 3d printer, the amount of fuel left in the tank etc. These things can not be figured out if they are in an enclosure and can not be physically accessed so we install these 10 segment bar lights to show how much approximately is the content left. This light bar has 10 different LED lights which are individually controlled by 10 input pins provided on the DIP package itself, you can drive this by a physical circuit or you can use it with the help of a microcontroller like Arduino or Raspberry Pi.

4. 2 Digit 7-Segment LED Display CC

The Seven segment displays are used frequently in our daily use appliances like microwave ovens, washing machines, air conditioners, etc. They are a simple and low cost but effective way to display numerical data like time or quantity. This a red color 2-digit 7-segment display module with CC configuration. 

5. Dot Matrix MAX7219 LED Display Module 

Display modules are widely used throughout the industry to show the data to the user or to give indication and warnings to the user. It makes the interface user friendly even if he is not of technical background and makes it easier for him to control the activity without the need of an expert. One main problem with LED displays is that they use many interfacing connections to connect with the microcontroller or development board you are using and thus it is left with shortage of pins to connect with other modules. This MAX7219 Dot Matrix Module LED display solves this problem the use of MAX7219 LED Display driver which converts the serial data coming from the microcontroller to the parallel data to the LED Matrix Module. Thus you can control all 64 LEDs by using just 3 pins on your microcontroller board. Also, this is a 4 in 1 dot matrix module which means it has four 8×8 LED display modules which is again only controlled by 3 connection wires. The data for each LED is stored in 8×8 RAM onboard and can be accessed individually.

6. Dot Matrix Display Module with Driver Control IC

The 8x8 Dot Matrix Display module consists of the 8x8 LED matrix display and the MAX7219 driver IC connected to it. It is very easy to interface with development boards like Arduino, Raspberry pi as 7219 IC uses only 3 pins to connect with your controller and drives all 64 LEDs in the module, thus saving the pins needed to connect all 64 LEDs. The LEDs are driven by 16 output pins of 7219 IC. The maximum number of LEDs light up at the same time is actually eight. As LEDs are arranged as 8×8 sets of rows and columns, the MAX7219 activates each column for a very short period of time and at the same time, it also drives each row. So, by rapidly switching through the columns and rows, the human eye will only notice a continuous light. This 8x8 LED Matrix module can be used in Outdoor displays, character design, displaying results, etc.

In India, Online Media Streaming is gaining popularity very rapidly especially due to the Global Pandemic. One more reason for this is the content that is provided on the OTT Platforms. You also get the benefit of saving your storage space as the minimum storage is used while watching online media and you can set the quality of media according to your network speed. The increased number of OTT Subscription leads Circuit Digest to find a new way of watching OTT media, through RaspberryPi .   If you don't know about RaspberryPi , it  is Linux based palm-size computer and can do all the tasks which a ‘normal’ computer can do. This is not the exact definition but this might give you some hint about it. The player we will be using to watch videos is Kodi media player .   Kodi is an open-source software media center, which allows us to access all kinds of content, including videos and music. We can run that content on any device like TV, laptop, phone, even in our Raspber...

Telegram is a cross-platform cloud-based instant messaging, videotelephony, and VoIP service with end-to-end-encrypted chat for secret chat only, whereas server-client / client-server encryption is used in cloud chat. In Today's world, everything is getting smart. Many new smart devices are being introduced in the commercial markets. Controlling all smart devices can be a handy job. IoTDesignPro comes with a different way of handling your smart devices. Unlike other social media apps, Telegram allows users to share any kind of open-source content. It announced the Telegram bot API in 2015, which lets third parties create telegram bots for ESP32 that utilize the messaging application as their main communication interface. This means that we can control any smart device with Telegram only. Previously, IotDesignPro also did some projects with the telegram app like Using Telegram Bot with Raspberry Pi: Sharing Text and Files Raspberry Pi GPIO control using Telegram App You might find...
