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.

What happens if a voltage between 1.5 and 3 volts is applied to a digital pin?

What is the significance of the digital read function in Arduino?

How can you visualize the state of a digital pin in the Arduino IDE?

Describe the relationship between voltage levels and digital states in Arduino.
