Hello, in the episode “Ben heck makes motion detecting hand sanitizer you use a board you call the LM36 audio amplifier. I can’t seem to find this board anywhere; could you provide information on how one could procure one of these devices? I have a similar need to play a small voice file with an Arduino and the only other device I can find that seems to fit my needs is the Adafruit Wave Shield for Arduino Kit - v1.1. Thanks for any help you can provide!
