Understanding HIGH and LOW Arduino Pin States :: Open Source Hardware Group Arduino Tutorials

The video tutorial explains the concepts of low and high digital pin states on an Arduino board. It covers how to determine these states using the Atmel 328 microcontroller's data sheet, focusing on voltage thresholds for low and high states. The tutorial also includes a practical demonstration using the Arduino IDE to read voltages from a potentiometer and apply them to a digital input pin, illustrating how to interpret the digital state based on voltage levels.
