In this tutorial we will learn what RGB LED is and how to use it with the Arduino Board.

There are few functions so useful that you find them everywhere. The ‘for loop’ is an example of this type. A For Loop repeats an action for a specified number of iterations, reducing the lines of code that need to be written thus making the programmers life easier. In this example we are setting out […]

In the last lesson we learned about the “If statement”. The “If statement” was the perfect choice for setting up instructions to run only when certain conditions are met. “If 30 seconds has passed – stop the heating element” or “If the sensor perceives a wall – turn 180 Degrees”. This lesson will expand on […]

Lets expand the repertoire of output that we can use by looking at the function analogWrite(). I experienced much confusion with analogWrite(), because I suspected that it had to do with the analog pins on the Arduino. The function, however, has nothing to do with the analog pins. There are 5 pins on most Arduino […]

In the last lesson you learned about using the analogRead() function to collect data from a sensor connected to one of the Arduino’ analog pins. The range of data we received from the analogRead() function, was mapped from 0 to 1023. What if we wanted to know the actual voltage being applied at the pin? […]

Knowing if something is on or off can be extremely useful, but often you will want to know more. How bright is the light? How fast is the satellite moving? These types of answers are often analog – they cover a large range of values, not just on or off. The Arduino handles analogs inputs […]

As simple as it may seem, knowing when something is either on or off can be a great tool to designing something useful. Answers to the following questions are what this lesson plans to tackle: Is a button being pressed? Has a switch been turned on? What is my on/off sensor status? When you can […]

The first program you usually write when learning a new programming language is called “Hello World”. The program outputs those words as its only function. When learning to program micro-controllers such as the Arduino, the equivalent of “Hello World” is a program that blinks an LED. Guess what it is called – Blink. You Will […]

IDE stands for Integrated Development Environment. Pretty fancy sounding, and should make you feel smart anytime you use it. The IDE is a text editor like program that allows you to write computer code for your Arduino board. When you open up the Arduino program, you are opening the IDE. It is intentionally stream lined […]

We are going to download, install, and set some preferences for the Arduino IDE on a PC. I’m running this on a computer that is a Windows 8 machine, maybe like 8.1 or something like that. Windows 10 is just coming out, and maybe by the time you are reading this, it is Windows 2000, […]
