Overview / Usage

Last year I made this sunglass bot with the help of my two other friends. A Sun Glass that automatically detects light intensity and closes or opens it's black glass.
So from now on you don't need to worry about eyes, this Glass is here to automatically protect your eyes. And also Opens the glass for ease of viewing at low light.
This robot is made using Arduino and some basic parts.
Now We want to add some more features in this sunglass.We want to add an IR sensor to it so it will help blind peoples alot. It will then detect an obstacle From a distance and blind peoples can easily avoid obstacles without any harm.

Methodology / Approach

We'll make a voltage divider circuit and connect it with arduino. Now we know that LDR is a variable resistor and it's resistance value changes according to light intensity. So as our Resistor is 10k our value will be in between 0 to 1023 . If there is bright or a medium sun light the value will be less than 100. In room light the value will be something around 500 to 600. If too dark the amount will be 1023.
That's it and then connect Arduino UNO usb cable and connect to your pc or android to upload the code.��Push hard to remove the black glasses and glue them on a hard wire just like this. and then mound the servo and add a servo arm to glue it with the extra glass frame we made.��Power up the circuit and you should see the arduino light up.

Technologies Used

We have used 1 Arduino UNO , 1 Servo motor , 1 light dependent resistor , 10k Ohm Resistor and some connecting wires to make the circuit
