arduino if multiple conditions
How to check for different conditions in Arduino?
In this tutorial, we will discuss the use of the if statement to check for different conditions in Arduino. The if statement is used to check different conditions, if the condition is true, the code inside the if statement parenthesis will be executed; otherwise, not.
What are some common Arduino problems?
A common problem between Arduino users is trying to expand a project beyond only one Arduino board. Arduino boards only have a certain number of I/O pins and peripherals including Arduino shields take up several of those limited pins leaving little to none pins left for other uses.
Can an Arduino run multiple functions at the same time?
Not on an Arduino. It has a single core. It executes one instruction at a time. PC's that are capable of multithreading can be running several instructions at the same time, so they could be running multiple functions at the same time. But Arduino can't do that. Also note, they're just called functions. Not "void functions".
How to change output conditions based on changing input conditions?
Use an if statement to change the output conditions based on changing the input conditions. The if () statement is the most basic of all programming control structures. It allows you to make something happen or not, depending on whether a given condition is true or not. It looks like this:
Hardware Required
Arduino BoardPotentiometer or variable resistor arduino.cc
Code
In the code below, a variable called analogValue is used to store the data collected from a potentiometer connected to the board on analogPin 0. This data is then compared to a threshold value. If the analog value is found to be above the set threshold the built-in LED connected to digital pin 13 is turned on. If analogValue is found to be <(less t
