Arduino Based 12/24 Hr Led Digital Clock with RTC Module Added

Hello Friend, Today I Am Going to Show You How to Make a Big 6 Digit Led Digital Clock at Home Using Arduino/Atmel Microcontroller (Atmega8a, Atmega328p… ), and 19 Transistors Have Been Used in This Clock. Also, RTCModule Added in This Version, So Let’s Start

Componenet Required 

1. LED ( I used 148pcs )
2. Atmega8a/Atmega328p microcontroller
2. DS1307 RTC IC
3. 13 Pcs NPN Transistor ( I used BC547 )
4. 6Pcs PNP Transistor ( I used BC557/558)
5. 23Pcs 1k resistor
6. 2PCs 10k resistor
7. 2Pcs 470 Ohm Resistor
8. 4 Pcs Button switch
9. CR2032 Battery
10. CR2032 Battery Holder
11. 28 Pin IC Base
12. 8 Pin IC Base
13. 32.768 Khz Crystal
14. 16 Mhz Crystal
15. Some Wire
