Creating Line Follower and How it Works.

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.

Make Home Energy Saving

Creating an energy-efficient homes, must be done from the initial planning, starting from house plans will be made. We must calculate the sun, wind and so on. Calculating the sun, it is that the rooms of the house that we make, can all be exposed to sunlight during the day, so we did not need to turn on the lights during the day to illuminate the room in our house. With this, we will save the use of electricity to power the lights in the daytime.

Taking into account the wind direction, we can design the room to keep cool even though we did not use a fan or air conditioning, so if we have a room like this, it will help us save our home electricity consumption.

So, if we want to make energy-efficient homes, konseplah from scratch, designed it so that we get energy-efficient room space in our homes.
