So, let us start knowing it.ħ-Segment and 4-Digit 7-Segment Display Module:ħ Segment Display has seven segments in it and each segment has one LED inside it to display the numbers by lighting up the corresponding segments. 7-segments also have the advantage against poor lighting condition and can be viewed from lager angles than a normal LCD screen. LCD suffers from the drawback of having low character size and will be overkill for your project if you are just planning to display some numeric values. Today we will Interface 4-digit Seven Segment Display Module with Raspberry Pi and display Time over it.Īlthough 16x2 Alphanumeric LCD is much more comfortable than 7-segment display, there are few scenarios where a 7-segment display would come in handier than a LCD display. We have already learnt how to use a Alphanumeric LCD and a single segment 7-segment display with Raspberry pi. This is where we prefer to use 16x2 Alphanumeric LCD display or the 7-Segment display. But, it would always be not economical to use a LCD screen with PI for displaying small amount of data. There are many sensors which can detect certain parameters from the real time world and transfer it to a digital world and we analyse them viewing them either in a LCD screen or some other display. All this can be possible only if we know how to make it interact with the real world and analyse the data through some output device. With its high computational power it can work out wonders in hands of electronics hobbyists or students. You can even upload from within the Fritzing app.We all know that Raspberry Pi is a wonderful Development platform based on ARM microprocessor. Possibly my favorite part of Fritzing is the “code” view, which is a mini embedded IDE for your Arduino code. This is a mess to start with, but you can move components around, click on AutoRoute and voila you have a printable PCB. Make an exact digital replica of your physical breadboard, then tab over to the PCB view. The idea of Fritzing is simple, you start with the breadboard screen – simply search and drag in your components from the menu on the right. I hear the latest version has fixed some annoying bugs which crop up from time to time. I plan to as soon as is possible financially. Please do support the developers at if you can. If you are like me, however, and have neither the money nor the time it takes to compile the software, you are in luck, as the software is available for free.
You can also compile it yourself from source: GitHub Repo. This is the paid version, currently available from $8. The latest version is available for all platforms on the site. From breadboard to complete printable PCB the user-friendly interface helps with learning electronics.Fritzing is the best circuit creating tool for beginners, hands down.
