DIGITAL CLOCK USING ARDUINO
Component List :-
1. Atmega328p / Atmega8A
2.16Mhz Crystal
3. 22PF x2 Capecitors
4. 28 Pin Ic Base
5. Led (I Am Using 116 LEDs)
6. Zero PCB
7. Slide On Off switch
8. Push On-Off Switch (1 Pcs)
9. Push Button Switch (2 Pcs)
10. Resistors 100 Ohm (8 Pcs)
Additional Items
1. 3.7 Volt Li-Ion Battery
2. Li Ion Battery Charger
Step 1- Make Single Seven Segment - each line of seven segment is made with 4 LEDs connected in parallel connection, Cathode of all the LEDs are connected together and Anode of 4 LEDs of a group are connected with each other.
Step 2- Make 4 Such Seven Segments, and keep the Cathode of each seven segment saperate and connect then to a male header as shown in the fig below.
Step 3- Connect A segment of all the four Digits together and further connect them with male pin header as shown in the figure.similarly connect B segment of all the 4 Digits together as do it for all the A to G segments.
