My idea comes from my personal experience. As a design student, I usually work until late without taking a rest. It is not a healthy habit. So, I designed a smart lamp. Photo resistor connect with a green led. LED will light up when it is dark which can help people find the light button in darkness. Temperature sensor can detect the temp of light bulb. If its cool, the green led will light. Otherwise, the red led will light up and start to blink. This is an alarm to tell you to take a rest now!! Please watch the video below :)
