Nature has provided everything for us. including energy. But our needs have forced us to use too much energy. We forget, if nature has a balance. Like equilibrium predator and prey. If the equilibrium is changed, there will certainly have an effect. cause and effect. In the closely related nature hard. The energy was like that, if the energy of the Universe decreases faster calculations do not match, this will cause adverse effects. Good for us human beings and to nature itself. We must get back to nature and to follow the present equilibrium. That does not mean we are without electricity or other fuels. But we are frugal use .
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
