- The DFPlayer Mini is a compact MP3 player module with a powerful 3-watt amplifier built-in. Just load your high-quality MP3 files onto a microSD card and control playback easily with buttons. Each button, connected to an input pin on the DFPlayer, uses a unique resistor to trigger a specific MP3 file. What's great about this device is its stand-alone functionality. It doesn't need extra hardware to work. Simply power it with 5 volts, connect a speaker, and you're set with just some wires and buttons. The DFPlayer Mini: small in size, big in sound!

THIS IS Exactly what I was Looking for.. Perfect for my RoboCop Cosplay
THANK YOU VERY MUCH. (sorry just very very existing to see a solution being presented to me)
Hobo cop
I agree!! I needed this exact thing!!
Didn't know that you can switch files using resistors and buttons, ty
It's called a voltage ladder
Analog input. With Analog to digital converter on the pin.
Changing the resistor changes the voltage.
That causes a change in digital code produced by the ADC.
The software then reads the code and tests for values in different ranges.
This would make for such an awesome DIY sampler or instrument
Thats means you could probably use a thermistor
So it switches mp3. According to the temperature
Yeah really practical.
How ya gonna create the temperature required?
You might need temperatures below freezing and temperatures at 90°F.
Just a thought lol @@deang5622
@@deang5622Maybe he meant it was a nice idea for an audio thermometer ?
@@Apoplio Still silly.
@@deang5622 There is value in every idea !
Wow... Been looking for something like this... I wanted to build a horn that can blast friendly tones to warn pedestrians like duck sound or meows etc
I've got some real chunky rotary switches that would be sweeeet for this
keep em coming kapper
Lots of potential for switches that change the sound of a single button. Like you could wire a rotary switch with different resistors to the same button
Cool - thx for sharing!
What's the maximum duration of mp3? Can i play full music?
Nice
Actually, I also have a video about this. This module is great 👍
Very very interesting
Cool lil board TY
5 volts…procceeds to show a 3,7 V battery
If you start two identical units with two identical SD cards and two identical mp3 files at the same time, they drift apart each other about 1 second within 6 minutes playback. Seems to be a clock rate variance. No two units are identical.
How does it handle repeat presses? What happens if you attach a potentiometer to it and “swipe” across the resistance range?
The default setting immediately plays the next press. But you can change modes to play each press fully
What if ypu would like sterio with two speakers ?
Just had a weird TH-cam Video Disonance Moment (YVDM). I swear I just saw Mumbo-Jumbo explain the Tuned Skulk Sensors using Note Blocks...
😵💫
I want to build this device with 6 buttons, it doesn't work according to the video, can you help me?
Hey nice videos and projects, how can i make a toy for my daughters that s speaking like the one you showed me?i can make the audio no probs
Jukebox. For Barbie!!!
up to how many buttons possible to attach on the module?
I have a matrix button system based on 1 wire. EZ.
ASIC or MCU with proprietary firmware?
Resistor heracy.
Can we get in touch, I run an embedded training programs , and a maker space lets work together
That's a lot of current resistor upto 200 k? How large is the current(voltage)flow ? I don't believe it for such a smallest board modules.
It sounds like deceitful claim of voltage information we could troubleshoot some energetic mind.
I mean, even if the resistance is high, and there is a voltage drop, the board will only require very small voltages to register the incoming data. I am not an expert but I am pretty sure that the resistance range provided in the video isn’t especially suspicious. There doesn’t have to be significant power provided by the board in order for this to work it we would consider the board capable of registering very small voltages.
