Product Details
There are three buttons on the ISD1820 voice recording module which are REC, PLAYE and PLAYL. REC button is red in colour, unlike PLAYE and PLAYL which are black in colour. REC button as the name suggest is used to initiate the voice recording. The voice is recorded for the duration of time the REC button is kept hold (the maximum length of audio which can be recorded by the module is 20 seconds). When the REC button is released the module stops recording voice. By pressing PLAYE button whole speech can be played back. PLAYE button works on trigger mode. Whereas PLAYL button works on jog mode. Hence, the voice recording is played back for the duration of time PLAYL button is kept hold. As soon as the PLAYL button is released playback stops.
In the ISD1820 module flash memory is embedded on board used to save voice recordings. As this is a non-volatile memory, it can keep data stored even without power input. There is an internal audio amplifier in the module which is used to drive a speaker of up to 8 ohms 0.5W load.
