[@Smr20002]

How can I play more than one record? I want it to be depending on the sensor deduction

[@hughman8597]

Thank you for this video! I want to build a LoFi Sampler, i know it works without arduino, but with to be honest, is a lot cooler !! ;) As I said thanks for the video greetings and a lotta love from germany!

[@robojax]

Glad it was helpful!

[@RangaswamyBl]

Sir how to connect the speaker

[@murrayswan5305]

Thanks for the video. Could you advise me how to interface (for play_E only) 2 or more of these to one mega2560 r3 please. I would like to play each one independently controlled by the mega, Thanks

[@flifoxali7058]

can i record more than one voice and use it in code

[@robojax]

I have another tutorial for that. Search for it.

[@AyandaDube]

Greetings Q: I'm using the Arduino nano to do the servor motor control with reference to your video on arduino uno servor motor with buttons, and it only turning one if i pressed the second button doesn't do anything

[@robojax]

Hi, I am sorry this video is on sound . I appreciate if you post your comment with the video here youTu.be/7woqNH_qby4 and this way other will learn from related comment.

[@harmaberghuis9354]

Can i use the ISD1820 in combination with de HS-RS04. So i can rec a scream and play that ervery time when somebody comes too close to the sensor hs-rs04

[@robojax]

Yes that’s exactly one of the main way this should be used

[@rahwayohannes4181]

Great video as usual!!...Will this module allow me to record multiple messages and play them selectively depending on the situation using multiple sensors and arduino r3? Also can we configure the pins as "input_pullup" and play it just by changing the state of the pin without the use of voltage divider?

[@robojax]

Thanks. you may look at this sound recorder kzbin.info/www/bejne/gXXGY41qaKmtipI

[@koensampers5505]

Lets say i want to make Alexa is it possible with this module to convert the voice frequency and amps to string?

[@robojax]

Never used Alexa. So don't know. This is just recording and you can play and hear it. can't do anything with the recorded sound.

[@yudhavalkyrie7568]

how to auto play after record sir? like a toys or parot toys,, record play and waiting sound record and play again

[@robojax]

I have shown how to record and play. It is veyr simple. You may have noticed that we are setting Arduino pins as HIGH or LOW to make the board play or record. I have tones of videos. Check them out.

[@yudhavalkyrie7568]

@@robojax tutorial pliss use ardion and no arduino sir

[@kokthyelim9488]

Is there any way to connect microphone and speaker to arduino directly without using ISD1820? This is to use allow soft speaking person to be heard by others.

[@robojax]

Arduino does not have that kind of memory to store the data. Also it does not have that kind of sensitive input for microphone.

[@kokthyelim9488]

@@robojax thanks for the information

[@obtusemage2262]

Thank you for this info. How can I make it play the sounds at random intervals? I’m making a haunted painting for a friend and I want it to play ghost sounds at random times.

[@robojax]

You are welcome. It need some work. Try learning about rand() or random() and also array.

[@yogasanas]

Can I use just as a microphone output to speaker. I dont want any recording just use it as a microphone alone.

[@robojax]

No you can't. Microphone is directly connected to the chip and there is no out except the speaker which plays. See it here in page 20 robojax.com/learn/arduino/robojax-ISD1890-SoundRecorder_datasheet.pdf

[@yogasanas]

@@robojax i was able to do it by the jumper provided in the back side pins. it was damn easy.

[@sharathchandra3601]

Can I store the recorded audio into a variable and access its information?? Thank you

[@robojax]

Anything is stored will be on the module and not on arduino. Arduino is just triggering it .

[@DirtNerds]

can you use this breakout board stand alone?

[@robojax]

Yea of course and I believe I first demonstrated that . But a 5 volt output how can u use it? Or for input how can input LOW (0 zero volt) or hIGH (5 volt). Get Arduino for $4 or get it from Amazon if you need it quick and the whole new world will open to you. I have full course of Arduino. Search my channel.

[@조연서-c7z]

can we send recorded sound file to sd card module that is connected with arduino?

[@robojax]

No we can't . We can simply play and record.

[@robojax]

You have to provide error code.

[@WunderWaffles_]

If I wanted to skip the audio recording and use it just to play sound, would that work? (In conjunction with an SD card module for example).

[@robojax]

it can play only from itself. Not from external source.

[@WunderWaffles_]

@@robojax okay thank you

[@robojax]

You are welcome.

[@zk_6312]

I can't really see why you would to use arduino code to record when you can just press the record button. Unless you put it in a project box and the buttons are not accessible. The playback lines are useful though as I just created a project where motion is detected and the recorded message is played back. I do wish you could load a sound file on it though.

[@robojax]

this is used for automation. for example if an even happend, door opens, temperature increases or something else, then ou can trigger to record. Automation if what this is for. You want to record only if something happens and Arduino can do it for you. The same way play back.

[@RangaswamyBl]

😮

[@vvijayalakshmi6186]

I want to record more voices and used as instructions in my code is it possible?

[@robojax]

You can't. Only one recording.

[@BarnacleButtock]

There is another chip, ISD1700, which comes with a similar module and has multiple messages and longer record time.

[@k3ndro]

Hi there, very informative! Will the sound loop if you keep holding Play-L ?

[@robojax]

Hi, Yes it will. I believe i have demonstrated it in the video.

[@k3ndro]

i watched the video again. i don’t think you did. only released the button half way

[@k3ndro]

but if u say it loops then thats cool for me!

[@robojax]

push button doesn't have have "half way". it can be either ON or OFF. you should be okay.

[@Chintan0905]

Give me list of components required in this project

[@robojax]

I have. Show all them and explained it. Watch the full video and lean about them. Nothing is left without explaining

is it store voice only once

[@robojax]

Yes. Only once.

Hello sir, this video help me a lot. But I would like the recorded audio safe in sd card with sd card module. What should I do? Your reply will be appreciated.

How to load already recorded sound to this device?

[@robojax]

Not possible. It can accept sound only from Microphone. You can however modify, remove microphone and connect 3.5mm audio jack to your device (phone or computer) then connect other side of the connector to the input of microphone via a potentiometer so the match the audio level. Then you can record it.

[@modelSUB]

Hello Robojax and thanks for your interesting video. Please can you tell us what is the potentiometer value and how to connect to the ISD1820 sound device and match the audio level? A schematic drawing wiil be very well received. Many thanks again and have a nice day!

how much it can record ??? i want to record a 9hours wav file sampled at a rate = 16Khz

[@robojax]

do google search. 9 hours is to be recorded on SD card or hard drive. Or get digital recorder.

[@AChadi-ug9pg]

@@robojax i might get a digital recorder, would you recomend one for me that has this caracteristics ! Thank you

[@robojax]

I am not sure. it is doable but seems complicated. You are not only playing, but you are reordering. For storage there is no issue as there is SD card module for Arduino. But recording module you would have to search. I have no experience on that.

[@robojax]

Hi, I just found a shield that can do the recording and playing and it has SD or micro SD card.:www.aliexpress.com/wholesale?catId=0&initiative_id=AS_20190304100100&SearchText=mp3+shield

no schematic for the module. but you can draw it using free software.

Is it possible to raise the sound?

[@robojax]

You can add a $1 or $2 amplifier to amplify the sound.

Voice quality should be better and clear If you have any board which can give output in better and clear voice, I want to buy one.

[@robojax]

I just played the video to know if you are referring to video sound or the recorded. Yes the recorded quality is very low. you can buy it from AliExpress or eBay just search for ISD1820. Good luck.

20 seconds? It only records and plays for 8 seconds.

@@robojax I watched the whole thing. The default setup is 11 seconds. To get 20 seconds you need to change a resister on the board - you didn't show that at all. And all your samples were 5 to 6 seconds.
