I LIKE THIS PROJECT SIR. Q. HOW TO CLULATE 4-20 MILIAMP. FOR DISPLAY 0 T0 100 RANGE. 4 MILIAMP.. = 0 20 MILIAMP.= 100 SAW THIS DISPLAY

This project is based on arduino RTC module. It can be stored memory the real time. You can use normal LEDs but need to use same color and same brand of LEDs, If you have selected different kind of LEDs, some LEDs may be glowed than others. Most of arduino beginners had prepared this project and also successfully completed. I hope you can make this project and enjoy the leisure.

How exactly did you wire up the individual digits to the Arduino? Did you use a binary to 7 segment decoder or something?

There is no binary. simple code to on and off leds for number.

Sir can we add ic 4017 in this project for control display digits using only two pins of aurdino.

I liked this project very much and want to construct it. Kindly clear me one think is digital pin 13 of arduino connected to blinking leds ?

In the step you mentioned "IF YOU USE COMMON CATHODE LED DO THE CHANGES AS FOLLOWS" the 3rd picture is wrongly uploaded I think. Would you please confirm me.

I completed the connection according to your diagram, uploaded the code to Arduino and turned on the power. The clock does not run. But pushing the setup button increments the digit of the hour and minute and the digit is seen. Out of setup mode, the digits are no longer visible. Clock does not run again. Please advise.

Please help I'm trying to Making this clock. But on problem wich pin for segment a,b,c,d,e,f,g And second minute hour. When i put the code ardiuno uno all Digital pin are blinked.i can't solve plese tell me. my need a complete circuit diagram

hai what itis aproblem please give solved Arduino: 1.8.13 (Windows 7), Board: "Arduino Uno" led_clock_codes:31:10: fatal error: RTClib.h: No such file or directory #include "RTClib.h" ^~~~~~~~~~ compilation terminated. exit status 1 RTClib.h: No such file or directory This report would have more information with "Show verbose output during compilation" option enabled in File -> Preferences.

Hello, what is the purpose of the bc547 npn transistors that come out of the pins of the arduino and go directly to the segments A-B-C etc, it is so that the leds light up with brightness, month you can explain it.

I have created from ds3231.I have a connection errors witch was not installed.That's why all the lights were blinking on. Finally I success. Very good Good project.
