Voice recorder 20SECONDS and playback easy just add dc
Very small board about 1"x1", just supply 5VDC adaptor power or use any DC batteries and attach a small loudspeaker, you can start recording and playback rightaway. This has built-in microphone on board, so you do not need anything else. For example, record command dog will understand, then remotely playback the sound, so dog think it is from you, Good thing about this board i that the recording is stored on chip even after power removed! get several of them for project
