This free online course discusses the interfacing and programming of Arduino using blocks for coding.

Do you want to construct dynamic, fully working projects featuring LEDs, push buttons, and potentiometers? This course will teach you how to program Arduino boards without coding and use simulation instruments for Arduino applications on the free website Tinkercad. You will learn everything about this website, beginning with account creation and user interface design and concluding with coding and simulation of various electronic circuits.

Next, we cover the Arduino output basics, including Arduino digital output - LED control, dealing with multiple LEDs and breadboard and adjusting an LED brightness using Arduino analog output. You'll discover how to design the circuit in Tinkercad, making the right connections between the components, such as the Arduino board, the breadboard, and the LED. After that, we explain the block-based coding approach and run the simulation.

Finally, we explore Arduino input basics while describing how to read a push button using Arduino's digital input and read a potentiometer using Arduino's analog input. The procedure of connecting an RGB LED to the Arduino UNO and creating a simple program to modify its colour will be then described. Lastly, we discuss Serial Monitor and all its characteristics and applications. Improve your Arduino skills with this easily understood course, which enables you to test code without a physical board.
