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
First Make Led 7 Segment Display
6 Digit Common Anode Connection
6 Digit Common Cathode Connection
Common 7 Seven Segment Connection with Transistor
Common Anode 6 Digit Connection with Transistor
Time Adjust Button Connection
Dot LED Connection
Main Circuit Diagram
All Wire Connection and How to Programme Step by Step Video Tutorial
Code and Library File
First Add “RTC ” Library in Arduino Library Folder
-:How to Add Any Arduino Library :-
Open ‘C’ Drive -> Then Open ‘Program File (X86)’ –> Then Open ‘Arduino’ Folder –> Open ‘Library’ Folder, and Finally Post Hare Arduino RTC Library Done!
Thank you
