In this article, we will interface a DC motor with an Arduino UNO using TinkerCAD software. Simulating a circuit before implementing the circuit manually helps to visualize the connections and it also provides the output under different conditions and constraints which would help to cross-check the output of the circuit implemented manually. What is Tinkercad? Tinkercad is a free, easy-to-use app for 3D design, electronics, and coding. It's used by teachers, kids, hobbyists, and designers to imagine, design, and make anything! Since it became available in 2011 it has become a popular platform for creating models for 3D printing, electronics simulation, coding as well as an entry-level introduction to constructive solid geometry in the schools. Why we are using it? We are using Tinkercad for saving money, learning & microcontroller coding. In this project, we have used the circuits facility of Tinkercad for simulating our project DC Motor Speed Control Using Arduino. The DC
