Many ways you can do to save on fuel use in our cars, save fuel consumption is a real step to conserve the use of petroleum. Some things we can do to conserve fuel our cars is to look at how to we drive our cars, like the quiet way we move the transmission, compatibility with the transmission speed (rpm) is one thing we can do to make our cars more efficient in fuel consumption . Another step that we can do to save fuel for cars is to avoid stepping on the gas pedal in a way all of a sudden, because it will make the fuel burn chamber will suck more and more, when engine speed is still low, so not all the fuel that will burn in. . This is one of the things that can cause us to be wasteful in the automobile fuel use. Other tips that we can do to conserve fuel in cars is to control the tire, a tire that has a size of less pressure to make our cars suffered fuel waste, by keeping the size of the tire pressure according to these specifications will help our cars to be fuel
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
