Discover what is meant by an analog value, see examples of analog components, and discover how to identify analog pins on an Arduino board in this video. Zahraa also explains how the Arduino board handles analog inputs.
- [Instructor] Oftentimes when using Arduino board for our…project, you might want to interface with an analog device…such as motors and temperature or light sensors.…Analog signals are simply signals…that have a continuous range of values.…In other words, they are not on or off…but rather of values in between.…An example is, let's say a temperature sensor…where you have a range of temperatures.…A light sensor, the light intensity changes.…
Motor, different speeds for the motor…and so on and so forth.…In the Arduino boards, the pins that are…for the analog inputs are identified with the letter A…so labels A0 to A5 for Arduino Uno.…For Arduino Uno, those are the only analog pins available.…In Arduino Mega, it has a 16 analog pins.…If you're interested in knowing how Arduino…handles analog inputs, I'll explain briefly about it.…
We are going to get little bit technical here so don't worry…if you find the information a little advanced.…When working with analog input signals,…the Arduino board uses Analog-to-Digital Converter, ADC.…
