Is the Arduino Nano original or similar ? I already got problems with Nano produced at China. To use them you need to take care with the installation of drivers communication for Windows.
Hello Seasickgooner,Probably is missing the library.You need to download the library for DFPlayer on following link: https://github.com/DFRobot/DFPlayer-Mini-mp3After this, unzip the file DFPlayer-Mini-mp3.master.zip on a temporary folder.It will be created a directory with the same name of zip file.Inside this directory, there is another one: DFPlayer_Mini_Mp3.This directory must be copied to Arduinos libraries folder in your computer.Try again and keep me informed.
Hello Nishchinta,I suppose that you have done everything according with the descriptions and you are using same bill of material.Another important thing is to use same libraries as I have mentioned in the project to be used in Arduino program.Take a look again in the schematics file (Frietzen). There are 03 momentary switches: 1) Mode: to define the operation modes (setup of time, talking minutes, talking completed hours).2) Minutes: to adjust/setup the minutes of time.3) Hours: to setup the hours of time.I recommend first you setup the time. Adjust the hours and minutes. After this change the mode of operation using switch 1 for what mode you prefer.Related to volume:1) Take care what kind of loudspeaker you are using. I was using a 2W x 4 Ohms.2) Try to increase the volume on the foll...see more »Hello Nishchinta,I suppose that you have done everything according with the descriptions and you are using same bill of material.Another important thing is to use same libraries as I have mentioned in the project to be used in Arduino program.Take a look again in the schematics file (Frietzen).

Hello, Seasickgooner,The code is in the file Talking_Clock_V2_0.inoRead again the project you will find it for download.
Great idea !! It would be useful for me all mornings !!

Talking Clock with ArduinoView Instructable »
Congratulations!! Excellent job!!
Hello, Davy,Thank you very much for your feedback!I am not a specialist, I am really an enthusiast of this technology that help us to learn more, to be curious, to be inventive, to be better than yesterday!Everyone is a beginner in something because we do not know everything. But we can learn!! All the time!Regards,Luís
Great progress!!! I am really happy with that!!Please, update the following statement for all these instances in the program:.........shiftOut(dataPin, clockPin, LSBFIRST, ~255); //Reset the DISPLAY 4 (to avoid some flicking).........In fact, ~255 means 0 (zero). You can replace by this if you prefer!I think it will work this time ! :)
See the tutorial about libraries installation:https://learn.sparkfun.com/tutorials/installing-an-arduino-library
1) Download the library file dht11: https://github.com/adalton/arduino/blob/master/pro...2) Place the DHT library folder your <arduinosketchfolder>/libraries/dht11. 3) Restart the IDE of Arduino.
Yes, it is possible to use a Common Cathode display, but you need to update all instructions of the program.With right programming, you can control this hardware as you want!For example, the following statements to set the Display #1 must be updated.From:digitalWrite(latchPin, LOW); shiftOut(dataPin, clockPin, LSBFIRST, 8); //Set DISPLAY 1 shiftOut(dataPin, clockPin, LSBFIRST, ~num[dezenaHora]); //Set the Hour digitalWrite(latchPin, HIGH);To:digitalWrite(latchPin, LOW);shiftOut(dataPin, clockPin, LSBFIRST, ~8); //Set DISPLAY 1 shiftOut(dataPin, clockPin, LSBFIRST, num[dezenaHora]); //Set the Hour digitalWrite(latchPin, HIGH);The sign ~ inverts the signal from HIGH to LOW or vice versa.Try to update all statements related to setup of the digits of display.

Hello, Veigrillen,Any progress ?Did you revise the connections and find out what is the issue ?
Don't worry!You are almost there! :-)You need use a Common Anode LED display.Please, confirm this information and check again the wiring connections.
Good news, Veigrillen !!I do not see any issue if you use the DS3231 RTC. Both modules use I2C bus and you can apply same library.In fact the DS3231 is much more accurate than DS1307 !!Just take care with corresponding connections SDA, SCL, Vcc and GND.Take a look on this tutorial:http://tronixstuff.com/2014/12/01/tutorial-using-d...Let me know about your tests.
Veigrillen,Just another remind. Take a look at your module specification if the Vcc is 5V or 3.3V to avoid any problem when you connect it on Arduino.
Hello, Veigrillen,Thank you !! I hope you have success with this project.It sounds me there is some missing library.Did you install the following libraries into your Arduino folder ?Time (library for date & time)DS130RTC (library for the Real Time Clock)Wire (library used to support the RTC)dhtt11 (library for the sensor of Temperature and Humidity)If you have done that, please try the following:1) Download again the file "Digital_Clock_V1_English.ino".2) Open it on a word editor (WordPad, for example) and copy all the text.3) Create a new file on Arduino Software.4) Clean all the statements of new file and paste the text you have copíed on item #2.5) Recompile the program and inform me the results.Good luck!!

Que bom! Poste depois uma foto de sua montagem.
Akilal,You must use two additional 74HC595 (shift registers IC) in cascade and also the corresponding resistors. Each shift register output #9 must be connected to the serial data input #14 of next IC.The program must be updated to manage the data in the right sequence to control the segments of displays.Remember that you are transferring serial data to paralell output.An easier way is to use a display of 8 digits x 7 segments as I did in my stopwatch project:http://www.instructables.com/id/Stopwatch-Lap-Time...
Luciano, boa noite,Que ótimo que tenha gostado deste projeto. Obrigado!Utilizei a biblioteca "Bounce2" deste link: http://playground.arduino.cc/Code/BouncePara download direto, o link é este: https://github.com/thomasfredericks/Bounce-Arduino-Wiring/archive/master.zipFiz este programa há bastante tempo e não tive problemas com esta biblioteca.Para testar, recompilei hoje o programa em minha versão atual do Arduino (1.6.10) e não houve erros.Por favor, tente refazer o download da biblioteca e me informe os resultados.Abraços.
Great job!! Congrats and thank you !!
