Hello all, For a time I tried to build a, but with not good results due the voice module I was using for that. After many searches related to right hardware and also learn about how to use the appropriate libraries, I achieved my goals. I will present you my version of Talking Clock using Arduino with the module DFPlayer_Mini to play MP3/WAV files. There are many reasons to go further with this project! With more improvements and adding some features, it can turn a clock for people with some visual deficiency, for example! In this project all the 'voices' were made digitally in Portuguese because is my mother language and I do not see many projects focused on that and also is an opportunity to give a gift to my followers in Brazil.
But of course you can follow the project and learn how everything works and then you can prepare by yourself all the voices in your native language! This is really cool and part of fun!! Let's see that! Regards, LAGSILVA - Oct.2016 Step 1: Build List. These are the components you need: • Arduino (UNO-R3, Nano)• LED Display Catalex TM1637 (4 digits x 7 Segments) or equivalent • DFPlayer_Mini • MicroSD memory card (formated in FAT32) • Resistor 1K Ohm (2x) • Breadboard • Momentary Switch (3x) • Loudspeaker of 2W or 3W • Wire jumpers (male-male & male-female) • DC Power supply (9 Volts) Notes: • You can use any MicroSD memory card up to 32GB, but all the MP3 files I have used for the voices are less than 2 MB (two Megabytes) in total!! So, do not spend your money a using memory card with a huge capacity!
• I decided to not use a RTC (Real Time Clock) because I have included a very easy feature to adjust the hours and minutes and the Arduino is precise enough to count the time. Step 2: How to Prepare the MP3 Files for the Voices. For your digital clock speak the hours and minutes, you must prepare some voice files in MP3 format and record them into MicroSD memory card according with the following steps: • Amount of files you need I created 3 groups of voice files: • Hours group (24 files from 0 to 23)• Minutes group (60 files from 0 to 59)• General voice messages (03 setup messages and 01 for the bell ring & cukoo sound) The total were 88 files. Note: I decided to use this strategy to simplify the logic of the program, but of course you have more work to record the files.
That is a trade-off you must to evaluate before translate for your native language. • Naming the MP3 files All MP3 files must be recorded with file names within format 'xxxx.mp3'.
The files must be done with four digits, starting from '0000.mp3' to '0087.mp3' or another number considering the total amount of files in your language. • How to create the digitally voices I found out many sites on Internet to convert text to speache files. The bad news are most of them must be paid to generate the files. Cinema Company Malayalam Movie Song Thick Rap Mp3 Free Download. One interesting and very good example is the site. Try to use the live demo in your preferred language. In Portuguese in just write the time as '12:17' and the softaware will speak the time for you.
In English, just write '12:17pm', for example. The problem is how to save the files. You can find a reference for that on the site. My personal solution was to install a software on my computer to do this translation 'text-to-speache':. You can install it and start to convert your texts using a free period for evaluation and then you decided if you want buy it or not (around $20 USD).
Personally I bought it after evaluation time. Note: For special sounds or effects, a great site is the where you can save the files direct on MP3 standard.
I used it for the Cukoo Clock sound. Step 3: Assembly - Schematics - Arduino Program. The assembly is very easy! Just follow the schematics and take care with the wire connections.
For the program you must to install an additional library in your Arduino for the DFPlayer that you can download it on. For setup of time there are 03 momentary switches: • # 1: For the setup of the 03 modes of the clock. • # 2: To setup the minutes. • # 3: To setup the hours.
The 03 modes are: • Silence Mode: To adjust the time of the clock (hours & minutes). • Minute Mode: To speach every minute.
• Hour Mode: To speach only at whole hours and put the cuckoo sound on action (on period 8:00am to 8:00pm). The remaining minutes of the hour keep in silence.
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. Elsawin Final Code Keygens more. I was using a 2W x 4 Ohms. 2) Try to increase the volume on the following statement of Arduino program, changing the 24 to 30 at maximum: mp3_set_volume(24);//Set the volume (30 max) 3) Try to use a software for sound edition like Audacity to turn all sounds file louder.
A final question: how are you generating the sound files? Good luck, LAGSILVA.
I made these three alarms for myself, I wanted to be able to wake up with nature sounds, in a calm and relaxed way, not jumping after a brutal BIPBIPBIP and be stressed the whole day.
