When you see a new function, it's good to learn what arguments it requires and what output, if any, it will have. Even if you want to set pins 10 and 11 as OUTPUTs, that's not allowed by the function- it can only use two arguments. The required arguments for a function are designed by the person who coded the function, so you can't change what the arguments are without changing the function itself.įor example, pinMode() needs two arguments: pin number and OUTPUT, INPUT, or INPUT_PULLUP. When you have to give information to a function for it to work, the information you give it is an argument. That's a good thing, because it means a previous developer has hidden lots of complexity so you don't have to deal with it. Some functions are built-in to the programming environment you use, so you won't see exactly how they work. That is a tiny function that takes in information and modifies it. If you say x = 2, then the result will be 4. Some functions take in information, change it, and spit out something different. They're basically groups of code that run together. Without slowing down the program, the LED will only be turned off until the computer reaches the top of the loop again- less than 1/10th of a second later.įunctions are everywhere in programming. Why do you need the second delay? Because the loop() runs over and over again. For only 250 you get a well-built and fully functional board. The most important reason people chose Acton Blink Lite V2 is: If you are thinking about getting an electric board but arent ready to pay thousands of dollars, the Blink Lite V2 is probably the best option for you. To turn the LED off, you'll use digitalWrite() again with a LOW argument. Acton Blink Lite V2 is ranked 13th while Yuneec E-GO 2 is ranked 16th.

The number you give to delay is measured in milliseconds, and 1000 milliseconds is one second. How much time? That's what the argument inside the delay() parentheses is for. There are no MIDDLE or MEDIUM commands.ĭelay() is a function that pauses your program for a set amount of time. digitalWrite also needs two arguments: pin number, and HIGH or LOW. In this loop, you use the digitalWrite() function to turn the LED on. You see them on line 5 of void loop occurs over and over again. PinMode commands happen between the curly braces that define the void setup(). You will learn more about the differences later. The first is the pin number, the second is whether that pin number should be used as an OUTPUT, INPUT, or INPUT_PULLUP. Choosing the Action Blink Lite, which is the World’s Lightest Electric Skateboard is a smart choice for younger people like children and teenagers. pinMode needs two arguments, or pieces of information, given to it. To do that in code, you use the pinMode() function.
