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:

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.

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.

Question:

Could this also be powered by a plug in variable voltage adaptor?

Answers:

  • Posted by Michael Lockhart on Wednesday, 27 January 2016

    There wouldn’t be an issue using a variable voltage adaptor, however the working voltage for the kit is between 2.7-4.5V’s and as such you would need to ensure the variable power supply is set to 4.5V’s as a maximum for the kit to work.

Question:

Is there a way of making this board play back a message twice in a 24hr period for as long as required (i'll need it to do this without any interference from me for two weeks)?

Answers:

  • Posted by Michael Lockhart on Tuesday, 20 January 2015

    You would need to use a microcontroller with a real time clock to keep track of the time. The Microcontroller will need to send a signal to the playback pin on the interface of the module at the chosen time(s). Once the microcontroller was set up with the correct timings for the sound to be played, you would be able to leave the circuit to play for the amount of days you wish.

Question:

Two questions: 1) If you hold the "play" button closed, will it still play normally, or do you have to release? 2) Will the board lose the recorded message if power is removed?

Answers:

  • Posted by Geoff Hampson on Monday, 6 October 2014
    The playback is triggered on the edge of the switch closing so hold the switch closed won't be a problem. It is however worth noting that there is an internal pull down resistor on the play input pin and this will draw some current whilst the switch is held pressed. The message is held in non-volatile memory so is retained even when the power is removed.
