Arduino Keypad Door Lock
hey, just a heads up, when pinning the transistor be sure to look up the pinout and double check before soldering. or you can do what i did and just look at the shape and trust the rest. then spend 3 days trouble shooting. the transistor in the diagram is inverted. aside from that learning experiance, this is an awesome project and im not sure how but i would like to post a video when i get the entire project done.
I am having a problem because the sound won't come out. Could it be that i have a 64ohm speaker?Also, is there any amplifier module that you recommend? Thanks. - Alkson
nice work !! sir can u please tell if i connect an audio amplifier instead of directly connecting the speaker to get more sound ?? - SyedS80
audio.pause(); pauses and unpauses the playback
Hello, thank you for the article, it is very helpful. I do tank on the bluetooth control, and I need the engine sounds. Please tell me: where you took them.
Hep! Thanks for this tuto its working, Ive a question, i would like to know if it possible that the sample play when you press the button, because at the moment le sample play when you release the button (LOW position) and there is a noise when you press (If you keep the HIGH position), do you have an idea ?Second point, Ive a keypad (3x4 with 7 pins) do I need to use de keypad librairy to use de 12 buttons or is it possible just with the TRMpcm library ?
Point 3: Is it possible to play the sample together ?
Jug Led level meter
what size for the breadboard? because you didn't list what size, i ended up getting one too small.
What type of 22k resistor do you need? how many wats? 1/4? 1/2?
Found the solution, it's because of the uncommented lines for the RTC.
Hi, I've encountered a problem where it says RTC is not running, I've done exactly as per your instructions and I've also checked my Tiny RTC to see if there is anything wrong with the connections and whatsoever but everything is fine. Can you help me?
Hello, thank you for your guide, it make my project finished. But i have one question, can we pause the wav when that wav was playing?Thank you
I am now making a workaround. I connected Nano+SD module to Mega 5V so that Mega is now powering on my Nano.. Well it's a strange idea, but all I need is background music with no control over it. Nano plays music by itself using SD library and Mega works with LCD using UTFT_SdRaw. Too bad I have to connect 2 SD cards now :D. My power bank is 5V/1A.
Hello Husham where download library UTFT_sdRaw, where the codec download and .raw file in Windows 10.
yes you can.please put in your mind that the quality of voice is bad ,so if you want a good quality ,try to connect arduino to MP3 serial module.
Hi,I didn't try this before so I have no idea.Sorry.
Hello there. Thank you for your guide, I made it using Uno R3 and SD module and it worked. Now I face a little problem with Mega 2560 + LCD screen with SD card reader. I am using library UTFT SdFat and UTFT_SdRaw to display images from SD card on LCD screen. TMRpcm library needs SD library to work but when I include it I get lots of errors that point to SD and SdFat. When I upload your code Mega 2560 plays from SD card without any problems. Is there any way to make TMRpcm work on SdFat only?
can i use arduino uno 3 as i have to make a voice comand blind helmet
3D Printed House in a Frame
I'm not sure if the library support atmega8.check below link for library feature :https://github.com/TMRh20/TMRpcm/wikiSupported devices: Arduino Uno, Nano, Mega, etc.
to get random number you need to use arduino random(min,max) command with switch/case statements .
Well, Music quality looks better than voice ,you can download "Wav Sample rate converter" software and try to change the samples per sec to 8000 and check.
Hi, i have an atmega8 with the arduino bootloader, this will work on it?thanks
