You've made it! You know, like, almost everything... about LEDs. Now go forth and put LEDs on whatever you please! And now... a dramatic reenactment of an LED without a current limiting resistor being over powered and burning itself out:
Yeah... it's not spectacular.

AVR-Based Serial Enabled LCDs Hookup Guide
The AVR-based Qwiic Serial Enabled LCDs are a simple and cost effective solution to include in your project. These screens are based on the HD44780 controller, and include ATmega328P with an Arduino compatible bootloader. They accept control commands via Serial, SPI and I2C (via PTH headers or Qwiic connector). In this tutorial, we will show examples of a simple setup and go through each communication option.
