The price of oil continues to rise. Though in our lives, oil has an important role, for example, is as a fuel. Our cars need oil. and that means spending money to buy fuel our cars. Each liter of oil that we consume for our cars, will likely continue to rise in price. Because oil prices continue to rise, probably due to the limited availability of oil. With gasoline prices now, we can calculate how much we spend on gasoline for our cars can still run our cars. What if the price of gasoline has increased 50% per liter, or 100%, could this happen?
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
