Introduction to Tinkercad Circuits

This video tutorial introduces Tinkercad as a tool for simulating Arduino circuits. It guides users through creating a new circuit, adding components like LEDs and resistors, and using jumper wires. The tutorial also covers programming the Arduino using Tinkercad's text editor and running simulations to test the code. The video emphasizes the convenience of Tinkercad for prototyping and testing before building physical circuits.

What should you do if you want to edit the circuit or code while the simulation is running?

Explain how to connect the Arduino to an external LED instead of the onboard LED.
