Token counter using Arduino and 7 segment Display

Hi here is one more interesting project Arduino based Token counter with 7 segment. 

7 segment is basically a combination of LEDs nothing more. We can connect it directly to Arduino too, but many pins will be engaged so we will use driver IC for 7 segment display. 

Now here is one more question that there are two types of 7 segment display. One is a common cathode (cathode terminal of all LEDs are common and apply +tive voltage to ON any segment). The second one is the common Anode which is the inverted version of CC. Here we are using CC 7 segment. 

Components List:

Arduino Uno

Seven Segment Display

LS7448

Push Button

LED

One more thing which I have used, that is the display driver IC for common cathode 74LS48. All connections are shown in the circuit diagram.

The same project I have completed with the PIC controller. 7 segment programming in MikroC for PIC is very easy but here in Arduino's case, it is very tricky so we are sharing with Arduino also.
