Here is the reason why we should make energy efficient Our energy is limited, takes long time to make it back, for example to create oil, nature takes millions of years. Save energy, we also save our money, because expenditures that we do to buy it will be reduced, and we can use for our other needs. Save energy, is one solution to global warming. And there are many other reasons why we should 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
