what we doTopic: Line Follower RobotThe working of a line follower Robot is based on concept of sensing the white/Black line and accordingly controlling the motion of the Robot. To sense the line we need line detecting sensors and circuit to control motor using these sensors. In this tutorial we will be implementing a white line following robot. Soldering is defined as "the joining of metals by a fusion of alloys which have relatively low melting points". In other words, you use a metal that has a low melting point to adhere the surfaces to be soldered together.
