Did you use a Solar Panel ? If not, I just read an article on a blog titled: Earth 4 Energy - My Review , there to write about How To Make Inexpensive Home Energy By Building Your Own Solar Panels . The writing on these blogs can bring awareness to us, why we should use solar panels in our homes as an energy source. The blog is a post about Earth 4 Energy Review , there is written that by using solar panels for our homes, it turns out we've been doing a great savings in our finances. So maybe after reading an article in the blog can make you have a desire to use solar panels on your house. And in the end if you already get benefits from the use of solar panels, you can tell your neighbors to come to use it as well. Solar panels are an alternative energy source that uses solar energy to generate electricity. Even solar panels can also be used as a heated room. You can use the electricity generated by solar panels had been directly, or you can also store them in a battery. If
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
