About this course

This course teaches Arduino and its practical applications from scratch. Arduino is a board that reads digital and analog signals from sensors and controls the modules connected to it. It starts with the Arduino components, variables and the simulation program, then lighting an LED with a push button and getting to know the breadboard. Next you learn IF, Switch, For and While statements, arrays and functions, and you display data on the Serial Monitor. Then you work with sensors such as the light sensor, the temperature sensor, the motion sensor and the distance sensor, along with the servo motor, the DC motor, the LCD screen and the keypad. At the end you build a Smart Car project in several parts. The course suits beginners, engineering students and electronics and robotics hobbyists, and it needs no previous experience. Afterward you will be able to connect components, program them and build simple projects on your own. The teaching is practical and gradual, and you follow the lessons in order to move from the idea to the application step by step.
