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. We all know that Raspberry Pi is a wonderful Development platform based on ARM microprocessor.
