Things used in this project

Hardware components

Photon
Particle Photon
powerful little low power microcontroller, super easy to make a connected thing
×1
Adafruit Speaker - 3" Diameter - 4 Ohm 3 Watt
a 3w 4ohm speaker should be plenty loud for this! We'll use a small amp to power it
×1
Adafruit Mono 2.5W Class D Audio Amplifier - PAM8302
so you can be loud!
×1
Adafruit Electret Microphone Amplifier - MAX9814 with Auto Gain Control
I like this microphone because it adjusts the gain so you can use it from far away or close up easily!
×1
Adafruit Tactile Button switch
push to talk! fits in a breadboard!
×1
Adafruit Half-size breadboard
You might have a bunch of these laying around like me, if not they're super handy!
