Automatic Netflix Login For Your Smart TV & Fire TV Stick
This project uses an Arduino Pro Micro configured as a USB HID device to automatically enter login credentials for Netflix on a smart TV or Fire TV Stick.

This project transforms an Arduino Pro Micro into a Human Interface Device (HID) capable of interacting with a Smart TV or Amazon Fire TV Stick via a USB connection cable. Because the Arduino Pro Micro features an ATmega32U4 microcontroller with native USB communication capabilities, it can be programmed using the Arduino IDE to emulate a standard USB computer keyboard. When you plug the programmed Arduino Pro Micro into a compatible USB port on your smart TV or streaming stick, the microcontroller executes a pre-compiled sequence of instructions. Rather than processing physical button presses from a standard remote control, the system automatically simulates a precise series of keyboard keystrokes and timing delays. These emulated keystrokes navigate the on-screen user interface, select the appropriate input fields, and sequentially type out your login credentials. By handling the navigation and text entry routines automatically, the hardware bridges the gap between traditional microcontroller programming and consumer electronics automation, turning raw lines of code into automated physical inputs.

Frequently Asked Questions
No, a standard Arduino Uno lacks the native USB capabilities of the ATmega32U4 chip found on the Pro Micro, meaning it cannot easily emulate a USB keyboard to send keystrokes to your TV.
Yes, standard USB ports on smart TVs and streaming sticks provide sufficient power for a low-power microcontroller like the Arduino Pro Micro.
You will need to modify the character string arrays inside your Arduino IDE sketch and re-flash the compiled code onto the Arduino Pro Micro.
