ISD1820-based voice recording and playback module
This small module can record and play back up to 10 seconds of audio by default, although this can be changed by varying the value of one resistor.
See the article on the Junk Mail Repeller in the August 2019 issue for more details. Also used in the July 2021 Model Railway Level Crossing project.
