![]() Connect black wires from the top power rail to pins 12e, 14e, 16e, 18e, 20e, 22e, 24e, and 26e.Make sure they're all in column b, and don't leave any spaces between them. Add 7 more LEDs to the right of the first one.Find the LED in the parts list, and drag one onto the breadboard so it is connected to pins 12b and 13b.Add a black wire connecting pin 1j to the negative power rail on the top of the breadboard.Make sure you click the drop-down to change the units from kΩ to Ω. In the box at top right, change the resistor's resistance to 220Ω.Click and drag a resistor onto the breadboard so that it is connected to pins 1d and 1f. Following these conventions makes our circuit easier to understand when we look at it. While the color of the wire doesn't affect the circuit, black wires are usually used to - and red wires are used to connect to +. Since this wire is connected to ground (-) click on the drop down box to change its color to black.When you see the pin highlighted in red, click again. Move the mouse left until it is directly below row 1 on the breadboard, then click again.While you're drawing a wire, clicking the mouse when you aren't hovering over a connection point adds a bend in the wire. Click, move the mouse to a point about halfway between the Arduino and breadboard, and then click again. ![]() s in step 2, move the mouse to the GND pin on top of the Arduino.Press the delete key to remove the wire.Click on the wire you just added to select it. This prevents visual clutter and can help make your circuits easier to understand. Sometimes, it's helpful the bend wires before connecting them.Each row has 10 pins, labelled from a to j. On the simulated breadboard, notice that there are 30 rows of pins. Move the mouse to the bottom hole of row 1 on the breadboard, and when the hole is highlighted in red, click to connect the wire.When the GND pin is highlighted in red, click the mouse to begin connecting a wire. Hover the mouse cursor over the GND pin on the top of the Arduino.Click and drag an Arduino and a small breadboard onto the workspace. In the parts list at the right of the screen, scroll down until you the Breadboards and Microcontrollers.You’re now ready to build a binary counter! Just follow the steps below to get started. When the circuit design screen loads, click the Components drop-down box, and choose 'All'. Now, on the right side of the screen, click the ‘Create new Circuit’ button to get started. In the menu on the left side of the screen, click ‘Circuits’. Once you’ve done this, you’ll to taken to the Tinkercad dashboard. To get started with the simulator, go to and create a free account. It's a great first project for Arduino, or if you haven't used your Arduino it's a great way to get back into it. Once it's working, you can easily experiment with other sequences and effects. The project guides you through the steps required to make an 8-bit binary counter. This article will get you up and running with a simple project involving an Arduino simulator, a breadboard, and a handful of LEDs. It's actually interesting to do both of the projects if you have time, same application, one real world and one virtual. a separate one where you connect a real world Arduino to a breadboard then control LEDs ( ).this article which uses a browser based Arduino Simulator.Getting started with Arduino and want to try an easy project? This project takes about 45 minutes, is fun to do, and it even has blinking lights!
