However some boards, such as the Mini Pro, do not have this connector so the only way to connect to them is directly through the corresponding pins.
ARDUINO ANALOG TO DIGITAL CONVERTER SERIAL
Many models of Arduino boards have a USB or Micro USB connector connected to one of the serial ports, which simplifies the process of connecting to a computer. Virtually all Arduino boards have at least one UART unit. Sometimes you will see refer to the serial ports as UART. This requires at least two connectors to perform data communication, RX (reception) and TX (transmission).
Serial portsĪ port is the generic name with which we name interfaces, physical or virtual, that allow communication between two computers or devices.Ī serial port sends the information through a sequence of bits.

Therefore, the serial port is a fundamental component of a large number of Arduino projects, and it is one of the basic elements that we must learn in order to take full advantage of Arduino. There are endless possibilities in which the use of the serial port is required. Thanks to the serial port we can, for example, move the mouse Serial ports are the main way to communicate an Arduino board with a computer. The 10 bits of resolution means that it will map input voltages between 0 and 5 volts into integer values between. The arduino Nano has 8 analog inputs, each of them provides 10 bits of resolution. ADCĪn Analog to Digital Converter (ADC) is a very useful feature that converts an analog voltage on a pin to a digital number. PotenciometerĪ potentiometer is a simple knob that provides a variable resistance, which we can read into the Arduino board as an analog value. For this activity you must remember the concepts shown below.
