This record and playback kit allows a short (10 second) message to be recorded and played back at the push of a button. There is one button to play the message and another to re-record the message which can be done over and over again.

The board includes a status LED which indicates that recording is in progress or that playback has completed. Both the speaker and microphone are PCB mounted so the only flying leads are for the battery holder which takes 2 x AA batteries.

The recorded message is kept in non-volatile memory and is kept until it is overwritten, regardless of the kit being switched off.

Because the module shuts down when it is not in use the batteries will last a very long time. An interface connector is available for more advanced users that wish to access the control signals.

Features:

  • Interface connector which allows some of the more advanced options of the IC to be accessed.
  • Connection of remote (off board) switches for record & playback.
  • Access to the pins to part play a message or to use the looped play option.
  • Control by a micro-controller (for example Arduino or PIC) if required.
  • Access to the audio output signal, which can be used with a more powerful amplifier if required.

Question:

Another question ... is there a way to download the recording? Say I'm making a cushion, can I download a 10 second voice clip from my computer directly into a recorder, then just have a play switch (so I wouldn't need a microphone or record switch)? If so what is the best way - can I modify this kit, or maybe use the igloo wearble to program it? Many thanks, Sarah

    Hi Sarah, The record/Play back kit isn’t designed to allow you to download a sound to it, as such it wouldn’t be suitable. If it was a tune you wanted to play then the programmable music box may be better, https://www.kitronik.co.uk/2122-programmable-music-box-kit.html as this allows you to download a tune onto it. If you wanted to play a sound or someone talking you would need to look at using the LilyPad MP3 Player, this would allow you to add MP3 files and program the board to play the sound under a set trigger, https://www.kitronik.co.uk/4688-lilypad-mp3-player.html.

Question:

Can I use different play and record button / switches? If say I wanted to make a large face cushion - having the speaker (board) at the mouth and have the play and record switches where the eyes are - can I attach different switches from the board? Could I use conductive thread for this? and what is the code of the sewable switches I would need? Sorry if this is a silly question - am completely new to this and trying to work out what is possible! Many thanks, Sarah

  • Posted by Michael Lockhart on Tuesday, 7 February 2017

    Hi Sarah, Yes you can use any push to make switch, instead of the ones in the kit and it would be fine to mount these where every. You would just use normal wire to connect them to the PCB, ensuring that all the connections are made correctly. Conductive thread wouldn’t be a suitable option as you aren’t able to solder this to the PCB and the PCB doesn’t have the correct contacts to allow a solid connection with the thread.

Question:

Item 2149. How do you lengthen the message to 15 or 20 seconds?

Answers:

  • Posted by Michael Lockhart on Tuesday, 24 January 2017

    Hi Ray, The maximum record time you likely to get is around 16 seconds, you would alter R5 from a 100K Ohm resistor to a 160K Ohm resistor. This would then give you a longer record time but would decrease the quality of the recording.

Question:

I need a product that I can record a short message on and then for it to play on its own, say every 10mins, all day, what do you suggest, do you have a product that would work like this. Thank you

    Hello, the record playback kit can play back a short (approximately 10 second) message, it does also have the option for looping the message although there wouldn’t be a delay in the loop. For your project it may be better to use an amp kit and connect it to a MP3 player with a file that has the required message and loop this sound file.

Posted by William, Thursday, 28 January 2016 on product Record Playback Kit

Question:

Two questions; 1) what are the dimensions of the board? 2) is there a way to set it up to play the sound if the button is released or set up a different switch? My intent is to place this in a small chest so when it opens it will play the recorded sound.
