save energy is required, if we save energy, we have showed that we matter to the world. But how to save energy ? to save energy, we can start saving with our use of electricity. why are we must save the electricity ? because of power needs fuel very much, so save the electricity, we will help reduce the fuel line. than with the electric utility, we can save energy by reducing the use of our car. we can use public transport, to go to the office, school, campus. We can walk to places close to. so we can save energy and also while doing sports. goods that use energy sparingly, is also an option to save energy. So we choose the electronic energy sparing before buying a electronic . With saving energy at our home, we can also save our money. So let us save energy
Robot line follower is a robot that is designed to be able to walk following the color of the line. Of course this requires basic knowledge of programming. In a line follower robot, we need a color sensor that will be used to detect line colors. Usually to distinguish between black and white. This color sensor, we can use infra red sensors, or can also use the LDR. Once we have a color sensor to detect the line, then we need the brain to make the robot can walk along the line. We can make it with an analog circuit, or with an IC that we will later fill with the program. To charge IC from line follower control, we can use arduino or by using Asembler programming. To learn this program, we must know the basics of logic. If we have the desire and sincerity in learning, to make a line follower is not a difficult thing. To make it easier we have a description of line follower, I took this from youtube video about lne follower. May be useful. link video : https://www.youtub
