A pair of sunglasses that automatically detects light intensity and closes or opens its black shade. So from now on, you don't need to worry about eyes. Instead, this pair of glasses is here to automatically protect your eyes and also open the shades for ease of viewing at low light. This robot is made using Arduino and some basic parts. Sounds cool, isn't it? Update: This robot has been Featured as TOP PROJECT on HAckSpace Magazine   https://hackspace.raspberrypi.org/issues/9 Step 1: Parts 1x Arduino Pro Mini (5v 16 MHz) 1x micro servo motor (any model is good but it needs to be small) 1x LDR (light dependent resistor) 1x 10k ohm resistor a pair of sunglasses For programming, you'll need a USB to TTl converter or Arduino Uno. I'll upload code using an Uno. Step 2: Principle We'll make a voltage divider circuit and connect it with Arduino. Now we know that LDR is a variable...
