Thank you so much for making this! This was extremely helpful in my project. If I wanted to add neopixels to this code to turn on only when sound is being played. Would I be connecting it to the dfplayer or the Arduino?

Hello Rachel and thankyou very much for teaching us some coding with the arduino. I have this very large dragon head that is made of paper mache & has led lights in the eyes and mouth (seperate circuits) that i want to attach to my wall. The lights are currently operated by 3AA batteries (4.5v) on each LED light circuit. I have managed to get your random sound effect player working great, but I would like it to somehow integrate with the led light circuit, so the arduino controls the lights on and off too when the motion is detected with playing the sound & lights. How would i go about this? (NOOB here). Thanks for reading this if you have time.

thanks for sharing.. can you make it an IOT by connecting that device into smartphones using bluetooth? by the uSe of MIT APP INVENTOR can you make a video about the block code of that also? thankies

Thank you for the great video! I have one question: What if I want the 3-second sound to repeat if motion is still present? Meaning, that if a person stays for longer than a few seconds the same sound loops. Right now, I see the option sensor is detecting that motion is still present, but the MP3 player automatically turns off after the 3 seconds of the sound bite as played.

Hi Rachel. The resistor you've talked about @7:15 is not for "smoothing" things. The thing is the DFPlayer inputs are not 5V tolerant and you need logic level shifting to not destroy those inputs. It is indicated (though it does not really stand out) in the datasheet. Even though the entire module is powered with 5V, the inputs can only accept 3.3V maximum. A bare minimal level shifter (from a 5V output) is a 2/3 resistor divider, e.g. 1k / 2.2k ohms - you can also build one with a PNP transistor or a P-channel MOSFET. The 5V input (Rx) of the Arduino however can cope with the 3.3V level and take it as a logic one. However it is close to the minimal value for a logic one (see the datasheet of the ATmega328 for reference).

You can use the busy pin to let the Arduino know the audio is playing so you don’t have to have a fixed value delay.

You seem really knowledgeable about this stuff maybe you can help me with a project that I'm trying to figure out. I'm trying to set up a display where three witches perform the scene from Macbeth. Each witch would need to speak her lines in turn and then all three of them speaking the communal lines. I know I will need servo motors for the jaw movement and head movement but how do I sync everything together in a performance?

Hi Rachel, I find your videos great! I particularly like how you really explain everything step by step. Question: Can you make a video about how you can create an animated mouth movement using Arduino of course. So a moving mouth that runs in sync with the voice? Needed it for my Halloween project 😁.

As a complete noob to Arduino, I was able to get this project working pretty easily. Thank you for the clear plans and directions. I would love to install this in a prop I made but as it is using a breadboard it has very loose connections and the wiring is a mess. Could you make a video on how to make this for a more permanant install maybe using a nano or othe rmeans to be able to solder it together and make it more compact?

I might have missed it but does the PIR have a test mode like a full motion sensor? It only stays on for a couple seconds then resets. I have all these parts but the player and I was wondering about using sounds, so this is perfect. Can you use multiple sensors? Like one on the front and back with different audio outputs?
@RachelDeBarrosLive
5 ай бұрын
For the PIR sensor like the one I'm using, you can adjust the Time Delay, which is the length of time it remains HIGH before going LOW. To rock through the examples quickly, I set my Time Delay to the shortest time but you can increase the time so the sensor doesn't go LOW so fast. There's also a Sensitvity knob where you can adjust the distance it can sense (3-7 meters). You can certainly use more than one sensor and attach specific sounds to each.
