Hi, if i connect the vcc input of df miniplayer to a digital output pin of arduino and set that pin high, is is enough to run the speaker? Another question is that i did the same as the video using 9V battery and it worked,however after sometime speaker gives some slow noise and not any audio output,why did this happen?
Hi friend, could you answer a question for me please? If I install a momentary switch on the power side so that it turns off/on when the lid of a musical box is opened, I assume the audio track will start from the beginning each time? Is there a different way you would achieve this? Also, in your video the audio played immediately when power was applied, that is exactly what I need it to do to use it in a music box project. Is there something you had to do to make that happen or is that a function of it's factory design? Thank you.
Hi friend 😊, its good for musical box project. When we gave power, it takes 2 to 3 seconds for audio playing. It always start from beginning each time.
Can you please explain why you added the jumper between the second ground connection and the AD key. I had it working without doing that but now I can't seem to get it to stay on and wondering if I need this or new board
@@fairelectro I added a second button, io1 goes to positive end of button, io2 too. The grounds meet up and it adds previous, volume up hold, next, volume down function. Do you know if there is a pause? And thank you. Project for my son
Hello friend, Do you have a video (and a list of parts) showing a voice recording loop, but with a strong volume from the speaker (about 90 decibels), and activation by a dry contact/open normal button?
If you really want to only play it once at start up, you can use a transistor that turn off when a current is applied. A capacitor and a resistor would provide the "turn off" signal. You can tune the time it takes to turn off the transistor by using different capacitor/resistor values. If price is not a problem, just use an arduino or something else, you can even add more functionalities. Lastly, read the DFPlayer's datasheet. This chip packs a lot of functions usable with only resistors and button. Maybe you can do what you want easily.
That's my question too. Could you tell me if you place more than one song on the card, if when the first song ends it automatically plays the next song?
thank you for your kind reply could you please describe how you put the audio files in to memory card ? I mean did you put the sound clip in to a folder or out of folder also I renamed it 001.mp3, 0000.mp3, 100.mp3 and still not working I appreciate your help @@fairelectro
@@fairelectro Yes I know, I was wondering considering how cheap small displays are like 4 inch ones for $10. What would be the easiest way of making a, power on play video file, power off. If you wanted to put one in a book nook, or maybe in a model as a push button effect
@@fairelectro Yes, like an MP4, video and sound. It would be best if there was a switch. Turned it on, file started playing, and looped as long as the power was on. That way if you made a diorama or a book nook you could just press a button, show off your work, press the button to stop.
