  • 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.
