When you look in the mirror, who couldn’t use a few words of encouragement? Build a display inside a mirror to scroll custom affirmations you can read over your own reflection. This polished project comes together easily with a store-bought shadowbox frame and some see-through mirror material. You can build a simple version with a basic Arduino or compatible, or level it up using a NodeMCU (ESP8266 wifi board) in order to add more positive quotes to the mirror over the internet.
