7 Segment Display Interfacing

This is a straightforward zero to 9 counter circuit created victimization Arduino! Here, a regular cathode 7-segment semiconductor show is connected to Arduino for displaying the digits.

The code (Arduino sketch) permits controller increment of the counter from zero to 9.

The whole circuit is going to be supercharged from a customary 9V PP3/6F22 battery, or from any applicable Arduino power device.

The seven-phase show is, in fact, Associate in a Nursing awfully easy device. it’s a combination of eight LEDs (the notational system -DP- is that the 8th), which could be organized so as that utterly completely different mixtures are going to be accustomed build numerical digits.

Circuit Schematics

The connections that square measure finished seven section show square measure given below:

PIN1 or E to PIN half dozen of ARDUINO UNO

PIN2 or D to PIN five

PIN4 or C to PIN four

PIN5 or H or displaced person to PIN nine ///not required as we tend to don’t seem to be mistreatment the mathematical notation

PIN6 or B to PIN three

PIN7 or A to PIN a pair of

PIN9 or F to PIN seven

PIN10 or G to PIN eight

PIN3 or PIN8 or CC to ground through a 100Ω electrical device.
