Product overview

Carduino UNO R3 is the latest version of the Arduino USB series, Carduino UNO R3 and Arduino UNO R3 AREF edge increases the SDA and SCL ports, in addition, the edge of the RESET and two new port. A port is IOREF, it can adapt extension plate motherboard voltage, another empty port reserved for future expansion. Carduino UNO R3 compatible with sensors expansion board v5.0 and adapt to the new extension board can use additional port. Carduino control core can be used to do the project development can also be done USB connection directly to the PC and the interactions between the computer and run in the open source IDE development environment, the software can be downloaded in the Arduino website directly (support for Windows, Linux, and Max system), the processor core is ATmega328, at the same time with 14 digital input/output (including six road can be used as a PWM output), 6 road analog input, a 16 MHZ crystal oscillator, a USB port, and a power socket, a ICSP headers and a reset button.

specification

  • Working voltage:5V
  • When input voltage: plug in the USB without external power supply or external 7 v ~ 12 v DC input
  • Output voltage: 5 V DC output and 3.3 V DC output and external power input
  • microprocessor:ATmega328
  • Bootloader:Carduino Uno
  • clock frequency:16 MHz
  • input voltage:7-12V(recommended)
  • input voltage: 6 to 20 v (limit)
  • Support USB protocol and power supply (without external power supply)
  • Support the ISP download function.
  • 14 digital I/o port: working voltage is 5 v, each all the way to the output and access the maximum current is 40 ma.

(1)Serial signal RX (0), TX: (1) with the internal ATmega8U2 USB - to - TTL chips are linked together, provide TTL serial port receiving signal voltage level.
(2)External interrupt (2 and 3) : raise the interrupt, falling edge along the Settings, or trigger at the same time.
(3)Pulse width modulation PWM (3, 5, 6, 9, 10 and 11) : provide 6 road 8 PWM output.
(4)SPI (10 (SS), 11 (MOSI), 12 (MISO), 13 (SCK)) : SPI communication interface.
(5)Leds (13) : the Arduino specially used to test the LED reservation interface, when the output is high light LED, vice output for low LED goes out.

  • No.6 analog input A0 to A5: each all the way with the resolution of the 10) (i.e., there are 1024 different input values, the default input signal range is 0 to 5 v
  • AREF:reference voltage of the analog input signal.
  • Reset:Signal for low reset microcontroller chip.
  • Dc current:40mA(I/O)
  • Dc current:50mA(3.3V)
  • Flash Memory: 32 KB (ATmega328 0.5 KB to boot)
  • SRAM:2 KB (ATmega328)
  • EEPROM:1 KB (ATmega328)
  • 尺寸:75x55x15mm

Application of routine

This program is used to test CarDuino UNO R3 all I/O port state

sample code

int val;
int i;
int ledpin[]={1,3,5,7,9,11,13,15,17,19,21};
int ledpin1[]={0,2,4,6,8,10,12,14,16,18,20,22};
void setup()
{  
   for(i=0;i<13;i++)
    {
      pinMode(ledpin[i],OUTPUT);
      pinMode(ledpin1[i],OUTPUT);
    }
}

void loop()
{
  for(val=0;val<13;val++)
    digitalWrite(ledpin[val],HIGH);
  for(val=0;val<13;val++)
    digitalWrite(ledpin1[val],LOW);
    delay(500);                    
  for(val=0;val<13;val++)
    digitalWrite(ledpin[val],LOW);
  for(val=0;val<13;val++)
    digitalWrite(ledpin1[val],HIGH);
    delay(500);                     
}
