PROJECT – 7 Segment Display
In this
tutorial you will learn how to use 7 Segment with Arduino and making a count
from 0 to 9.
STEP – 1 Components
Components
Required:-
1.
Arduino Uno
2.
Breadboard
3.
7 Segment
4.
Wires.
5.
Resistance.
6.
Slide Button.
STEP – 2: Circuit
 |
| The connections are pretty easy, see the image above with the breadboard circuit schematic. |
STEP – 3 : Code
int a = 7;
int b = 6;
int c = 4;
int d = 3;
int e = 2;
