If you read my hero academia manga or watch my hero academia anime, you must know a charracter named shota aizawa. Shota Aizawa also known as the Eraser Head, is a Pro Hero and the homeroom teacher of U.A.'s Class 1-A. Shota's Quirk gives him the ability to nullify another person's Quirk by looking at the user. His ability deactivates if Shota blinks or if his line of sight is obstructed. Eraser Head can be recognized by the yellow goggles he wears around his neck, hidden by his scarf.

I was inspired from this charracter and I wanted to control the appliance such as lamp in my home with eye blink. This approach of controlling appliance(Lamp) with eye blink would be especially useful for a wide range of people, starting with those who are almost completely paralyzed to completely healthy persons.

    Wiring Diagram for Transmitter (Eraser Head Goggles)

    The following image shows the complete wiring diagram of transmitter using Arduino Nano. After connecting all components then I inserted all these components into the enclosure and sealed it completely using hotglue.

    The Ir sensor detects the blink to switch ON the lamp and if the ir sensor detects the blink again the switch will OFF.

    NRF24L01 2.4 GHz Transceiver Module can be used for wireless communications at up to 100 meters.T he operating voltage of the module is from 1.9 to 3.6V, but the good thing is that the other pins tolerate 5V logic. The module communicates using SPI protocol. You should make looking at the arduino pin connector model SPI pins.

    Transmitter (Eraser Head Goggles) Code

    You need to do is install RF24 Library. You will get an error if you dont install.

    When you want to add a new library into your Arduino IDE. Go to the directory where you have downloaded the ZIP file of the library. Extract the ZIP file with all its folder structure in a temporary folder, then select the main folder, that should have the library name. Copy it in the “libraries” folder inside your sketchbook.

    Connect the arduino nano and upload the given program on your arduino nano.
