Limitations of existing energy, has encouraged people to make new discoveries about energy. We all know that oil energy mi bu we are very limited, while oil demand is huge. This is why scientists do research to find new energy sources. To support this, we can use energy-efficient, this is a real step to one of the problems people in the world, namely the energy crisis. read some good news about the discovery energialternativ sources other than oil, which can be used for fuel, namely oil from Jatropha curcas. Some experts have been able to cultivate Jatropha curcas plant to produce oil that can be used as fuel for engines. of course this is good news, when we are faced with the problem of energy crisis that hit us. the discovery of jatropha curcas plants that can produce oil for fuel can be further developed and made petroleum as a substitute materials, with prices that much more cheaper production from petroleum cost more to produce.
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
