We've heard about the campaign to save energy. We are hopeful that we take part in real events that we do to save energy. Have you been doing real activities in order to save energy? This time we tried writing a real steps that we can use to save energy consumption. Some real steps we can do to save energy is included as follows: - Choosing energy-efficient electrical equipment. - Turn the timer off the television when we watch tv before bed. - Using publick transportation to go to work. - Depart with colleagues who work together. There are many more steps we can do to save energy, let us support energy-saving campaign, by taking our real steps to 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
