Arduino for Beginners - 2022 Complete Course - Introduction - Potentiometer- Analog Pins

The video tutorial begins by explaining the concept of binary states, high and low, as read from a push button. It then introduces the potentiometer, a sensor that provides a range of values rather than just two binary states. This is particularly useful for applications like volume control, where gradual adjustment is needed. The tutorial further explains the necessity of using analog pins to read the range of values from a potentiometer. In subsequent lessons, viewers will learn to add a potentiometer to a circuit, understand how analog pins function, and practice using the potentiometer.

What are the two states that a push button can read?

• On and Off

• Open and Close

• High and Low

• Start and Stop

What type of sensor provides a range of values instead of just binary states?

• Thermistor

• Photodiode

• Potentiometer

• Accelerometer

Why is a potentiometer useful for volume control?

• It can switch between two fixed volumes.

• It provides digital volume control.

• It allows gradual adjustment of volume.

• It can only mute or unmute the sound.

What do you need to use to read the range of values from a potentiometer?

• Binary pins

• Analog pins

• Digital pins

• Serial pins

What will students learn in the upcoming lessons regarding potentiometers?

• How to use digital pins with potentiometers

• How to add a potentiometer to a circuit and understand analog pins

• How to convert potentiometer values to binary

• How to use potentiometers for temperature control
