It can sometimes be frustrating to be working on a project only to find out that you have been doing it wrong the entire time (and now you've wasted money on components). While this experience is, regrettably, part of the learning process, shouldn't there be a way to eliminate the expense and mess?

Below is a simulation o a simple circuit with LEDs that demonstrates a way to avoid this problem. (you can click on the switches to turn them on and off)

If nothing appears above, click here.

Step 1: Tinkercad

There are a few programs available for download, such as ORCAD or EAGLE, these are both more processing intensive, and likely aimed toward professionals. Tinkercad is neither of these. It allows users to create 3D designs as well as circuits, and with the latter, you are able to both edit code for its components and run a simulation. Tinkercad is run by Autodesk, the same company who runs Instructables (the site you're on right now). Once you've made an account, navigate to your dashboard and proceed to the next step.

Step 2: Your First Project

At the top you'll see a button that says "create a new circuit." You'll want to click on it. Upon doing so, you'll be led to a new page with a menu on the right and a large workspace.

Feel free to fiddle around with some stuff here, and once you've made a project just click "start simulation."

Hopefully, this website will allow you to make what you couldn't before, or just give you a way to experiment before building something for real.
