2digital 7segment control with 74hc595n

here is a library that allows you to control 1 digital or 2digital 7segment with a 74hc595 you need to download .zip file library and add on arduino

---

schema

	default connection

(74hc595n) latchPin -> 4 (arduino)
(74hc595n) clockPin -> 3 (arduino)
(74hc595n) dataPin  -> 2 (arduino)
(74hc595n) segment1 -> 6 (arduino)
(74hc595n) segment2 -> 5 (arduino)

Examples

2digital_7segment send value on serial monitor

analog_print_value

---

for using

#include  "segment.h"

//déclare new instance
Segment m;

void setup()
{
	m.Initial();
	.....
	.....  //YOUR INSTRUCTION
	.....

}

void loop()
{
	m.clear_All();
	.....
	.....
	.....	//YOUR INSTRUCTION
	.....
	m.scree(parametre);
}

#include "segment.h" => it's important

Segment m; => for declare new instance

m.Initial (); => m.Initial syntax ((latchPin, dataPin, clockPin, segment1, segment2); If you do not give a parameter, it will use the default connection, or if you want to choose your own pin number as a parameter. Example: initial m (7,8,9,10,11);

m.clear_All (); => to disable all segments

m.screen (parameter); => function to display the parameter you gave, it is only partisan integer (int) if you have another variable convert it to int

 on parameter give "1" to turn on point segment of first digital segment
 on parameter give "2" to turn on point segment of second digital segment

you can look at examples sketch on your files library

in a future release

• to able to use 3 and 4 digit 7 segment
• new function to easily using the 7 segment
• try to create this library for micropython
