Analog Pins
In general, the analog pins are used for general purposes like supporting 10-bit analog-to-digital conversion (ADC) which is performed using analog the Read() function. These analog inputs can also be used as digital pins: analog input 0 as digital pin 14 through analog input 5 as digital pin 19. Analog pins are particularly helpful since they can store 0-255 bits which is not possible using digital pins. This feature is not available on every Arduino board.
- I2C(Inter-Integrated Circuit): These pins are present at numbers 4 (SDA) and 5 (SCL) and are used to perform I2C (TWI) communication. Note that we need to import the Wire library to use this protocol.
Overview of the Arduino UNO Components
Arduino is an incredibly important part of modern-day electronics. The ease with which these Arduino boards can be programmed makes them the best choice especially when it comes to integrating them with large-scale projects. In this article, we will get an overview of the basic components that make up an Arduino board. This will include talking about the brain of the Arduino i.e. the microcontroller, the pins, and the power supplies.
