Descrizione
This Starduino Uno R3 development board is produced by ALSRobot. The Arduino Compatible Uno is a microcontroller board based on the ATmega328. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.
Each of the 14 digital pins on the Uno can be used as an input or output, using pinMode(), digitalWrite(), and digitalRead() functions. They operate at 5 volts. Each pin can provide or receive a maximum of 40 mA and has an internal pull-up resistor (disconnected by default) of 20-50 kOhms. In addition, some pins have specialized functions:
— Serial: 0 (RX) and 1 (TX). Used to receive (RX) and transmit (TX) TTL serial data. These pins are connected to the corresponding pins of the ATmega8U2 USB-to-TTL Serial chip.
The Arduino Conmatible Uno has 6 analog inputs, labeled A0 through A5, each of which provide 10 bits of resolution.
Note: questa scheda di sviluppo Starduino è uguale ad Arduino UNO R3 e funziona con l’IDE di Arduino, ma ad un prezzo inferiore.
