LCD
Initially I started experimenting with a 4x20 LCD screen to display the initial welcome text that invites the audience to sigh. The four pins (SDA, SCL) on the side did not work, and I had to solder the wires to 11 pins on the back. The screen did not display text as expected at first, and this was resolved by adjusting the trimpot position at the backpack module, which changes the contrast of the display to show text clearly. However, when I re-soldered everything to assemble the mirror, the screen stopped working. I unfortunately had to give it up and opt for the OLED screen instead.
