Build an LED Switch Calendar for the New Year

It’s almost 2026 so some of you might be shopping for a new calendar. FriendlyWire.com offers a twist on the traditional calendar. Every day flip an LED switch and watch the current build, great beginner project with some lessons along the way.

The main idea of the calendar is simple: every day, we turn on an additional LED. When we connect all of these LEDs in parallel, then the total current that flows through this circuit gets bigger the more LEDs are turned on.

See the full build guide!
