pinMode, digitalWrite, delay: Arduino Course 4.2

This video tutorial introduces three essential functions for Arduino programming: pin mode, digital write, and delay. It demonstrates how to set up a circuit to blink an LED using these functions. The tutorial covers the basics of the Arduino IDE, including writing and verifying code. It explains the importance of setting pin modes, applying voltages, and using delays to control LED blinking. The lesson concludes with a review of the key concepts and a brief discussion on the significance of the 'Hello World' exercise in microcontroller programming.
