In about 2 minutes we’ve created exactly the same circuit, we’ve used the same exact code, and after hitting the “start simulation button”, we have a virtual version of exactly the same circuit. Next we’ll use the free online Arduino simulator software at TinkerCAD. So we’ve setup the circuit, we’ve programmed the code in the Arduino IDE, we’ve uploaded it, and now we have a real world, physical circuit that blinks the LED. Some say it’s your first project where you create a simple blinking LED circuit others claim it’s when you have an LCD display that says “Hello world!”įor our purposes, we are just trying to create the the most simple of circuits, so we are referring to the interpretation where you just have a blinking LED circuit. Now some people have different interpretations of what the famous “Hello World” circuit is. What does that actually mean? Let’s look at an example.

HOW to use popular Arduino simulator called Tinkercad (which is free)Īn Arduino simulator is a virtual representation of a real world Arduino circuit.Are you on the lookout for a good Arduino simulator? Wondering what an Arduino simulator is? We’ve gotten a lot of questions about Arduino simulators, and if a good simulator exists, so keep watching to find out more!
