Tiny:bit Line Follower is a robot that walks following a black line and does not leave the black line in the program accurately using a timer using code up to 8 times repeated and must be straight from the start line to the finish line. The junior code has something called a function so its function is the same as broadcast, the difference is that it is in the makcode, so every time you change lines you have to use a variable, for example from 0 then send the variable 1 to 8 times.
