Solar panel is one of energy alternative can be modified become electricity. Solar panels have been already be used at many homes. Because solar panel have many advantages. The some advantages from solar panel is below : Firts advantage from solar panel is environmentally friendly, Solar panel not cause climate changes. Because solar panel can do not emit harmful gases .Not like if we use energy from fossil such as coal , petroleum, etc. The energy source from solar panel is sun. Sunshine is available in abundance . Next advantages from solar panel is esay to install ad esay to maintenance. Easily obtained . We can afford it easily. etc Some of the advantages of solar panels making it the choice of many people . People like to use them . And a lot of them already have their own power at home . We do not need to think about the installation , because the seller would be happy to install for us . Try to see what your neighbors are using
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
