Intro to Arduino with TinkerCAD

To begin your journey coding, there are a few basic commands you need to master: Loops, Logic statements, conditions, inputs, math, variables, and counts.

Loops:

In coding when you ask a computer perform a command more often than not it will perform it and then stop. This is because the command has been completed and the computer reads this a finished. Code commands will typically work down from the top down like reading a book and will do each command once unless it says otherwise. The way commands are coded to repeat are called loops. Below you can see a few different types of loops. Depending on the condition and what you need to control, these different loops perform differently. A "on start" loop will loop a command and repeat that command forever until sopping the code. An "on start" loop will typically be placed at the beginning of a code and the rest of the code will be nested in it. A "forever" loop can be placed anywhere in a code and like its name states will repeat forever unless commanded otherwise or the program is turned off. A "repeat" loop is set to repeat a number of times. If you have something that is finite, you would use this loop function. There are also loops that can be set to repeat indefinitely, like the "on start" and "forever" commands but require a condition to be met. In this loop, you everything in the loop repeats only while the condition is true. Typically, you want all of your code for the rest of the project nested inside at least one of these loops so that it repeats for as long as you need it to.
