WEBVTT 00:00.000 --> 00:07.840 components of a robot. Learning objective, creating a new circuit in 00:07.840 --> 00:12.760 TinkerCAD, adding the Arduino Uno, writing and running the Blink code, 00:12.760 --> 00:19.440 simulation and experimentation. Hey there! In this video, we will walk through 00:19.440 --> 00:24.000 the simple process of using TinkerCAD to test the built-in LED on your Arduino 00:24.000 --> 00:31.720 board with a Blink test. Step 1. Open TinkerCAD. First, open TinkerCAD and create a 00:31.720 --> 00:38.240 new circuit. If you don't have a TinkerCAD account yet, sign up at TinkerCAD.com. 00:38.240 --> 00:45.400 Choose the type of account. Then, there are a number of ways to sign up, including 00:45.400 --> 00:51.200 email, Google or Apple Mail. Follow the on-screen instructions and fill the 00:51.200 --> 00:55.880 prompted detailed and sign-up into your TinkerCAD account. 01:03.080 --> 01:07.520 Here's the typical homepage, where you can see a lot of pre-built designs in 01:07.520 --> 01:11.280 the gallery. You can scroll through and change these designs if you're 01:11.280 --> 01:17.680 interested. There is a vast collection of circuits, 3D designs and code blocks 01:17.680 --> 01:24.880 for you to copy, edit and tinker with them. Step 2. Create a new circuit. Click 01:24.880 --> 01:29.720 create then, new circuit from the drop-down menu to create your first circuit. 01:29.720 --> 01:36.040 Step 3. Add the Arduino Uno. Now, we need to add an Arduino Uno to our 01:36.040 --> 01:39.800 workspace. Simply drag and drop it from the components panel on the right 01:39.800 --> 01:45.480 side of the screen. By default, the Arduino Uno has an inbuilt LED connected 01:45.480 --> 01:50.920 to pin 13, so we won't need to wire anything externally for this blank test. 01:50.920 --> 01:57.560 Step 4. Let's start coding. Now, let's open the code editor by clicking on 01:57.560 --> 02:03.040 code in the top right. TinkerCAD uses block-based coding by default, but for this 02:03.040 --> 02:09.480 test, we'll switch to text-based code. To do that, click on text at the top 02:09.480 --> 02:16.840 left of the code window. Step 5. The Blink Code. By default, the code for the 02:16.840 --> 02:22.680 inbuilt Blink test comes with the code editor. Let's understand the code. Here's 02:22.680 --> 02:29.440 a quick breakdown of the structure. In the setup, function, we configure pin 02:29.440 --> 02:36.440 13 as an output. In the loop, function, the LED turns on for one second, then 02:36.440 --> 02:41.240 off for another second, repeating this cycle indefinitely. The digital right 02:41.240 --> 02:47.400 function to control the LED and delay to set how long it stays on or off. 02:47.400 --> 02:52.120 TinkerCAD provides features like schematic sketches for the circuits you built 02:52.120 --> 02:56.560 that can be shared and printed when required, and it is useful while building 02:56.560 --> 03:01.320 complex circuit, involving multiple components, giving a visual representation 03:01.320 --> 03:07.720 that helps in prototyping. Step 6. Start the simulation. Once the code is in, 03:07.720 --> 03:14.480 click start simulation at the top right to run the circuit. Step 7. Observe the 03:14.480 --> 03:20.240 inbuilt LED. Great. You can see that the inbuilt LED on pin 13 is now blinking. 03:20.240 --> 03:27.080 This means your code is working. Step 8. Experiment with the code. If you'd like 03:27.080 --> 03:30.720 to experiment, you can adjust the delay times in the code to make the Blink 03:30.760 --> 03:40.720 faster or slower. The shorter the delay, the faster the Blink. Step 9. Explore and 03:40.720 --> 03:46.200 improvise. TinkerCAD allows to rename, share, and let others make a copy of your 03:46.200 --> 03:53.880 project for tinkering. TinkerCAD to test the built-in LED on an Arduino board is 03:53.880 --> 03:58.680 a simple and effective way to learn basic circuit simulation and coding. By 03:58.680 --> 04:03.080 following these steps, you can easily experiment with the Blink test and explore 04:03.080 --> 04:06.280 further Arduino projects.
