• Left side bar: “Circuits”

  

• Button: “Create a new circuit”

• Dropdown on right: change “Components - Basic” to “Starters - Arduino.

  

• Select “Breadboard” and drag it out (may lag, go slow).

  

• Change back to “Components - Basic”. Search for “potentiometer” if you can’t see it.

Tips

• The positive leg of the LED is longer - so you see it as bent in the picture.
• Pay attention to how the holes in the breadboard connect!
• Grab the white space on the background to move the whole assembly at the same time.
• Rotate a component is the icon in the upper left, just below the TinkerCad logo.

Example to Make

Here is an example with one light that repeats a cycle from off to dim to bright every 1.2 seconds.
