LED 13: It is an inbuild LED in the Arduino boards similar to that in Arduino Uno and mega. The LED is high when this pin is provided with a high signal. AREF: It is the reference voltage pin and is used with the function analog reference () in analog inputs. RESET: The reset ...
To use the AREF pin, resistorBR1 must be desoldered from the PCB. DAC1 and DAC2 - These pins provides true analog outputs with 12-bits resolution (4096 levels) with the analogWrite() function. These pins can be used to create an audio output using the Audio library. AREF - Reference...
I/O- All 54 digital bins on the Arduino 2560 can either be used as an input or an output, using pinMode(), digitalWrite(), and digitalRead() functions. They operate at 5 volts and each pin can provide and receive a maximum of 40 mA and has an internal...
Revision 2 of the Mega2560 board has a resistor pulling the 8U2 HWB line to ground, making it easier to put into DFU mode. Revision 3 of the board has the following new features: 1.0 pinout: added SDA and SCL pins that are near to the AREF pin and two other new pins placed near ...
Revision 2 of the Mega2560 board (A000047) has a resistor pulling the 8U2 HWB line to ground, making it easier to put into DFU mode. Revision 3 of the Arduino Mega 2560 board (A000067) has the following new features: 1.0 pinout: added SDA and SCL pins that are near to ...
The Arduino Mega 2560 is a microcontroller board based on the ATmega2560. It has 54 digital input/output pins (of which 15 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, ...
Please note that a pull-up resistor is needed when connecting SDA/SCL pins. Please refer to the examples for more informations. MEGA 2560 board has pull-up resistors on pins 20 - 21 onboard. I2C的Arduino库函数 begin() 初始化总线,作为主机或从机加入总线,带地址参数就是从机,不带就是主机 ...

Revision 2 of the Mega 2560 board has a resistor pulling the 8U2 HWB line to ground, making it easier to put into DFU mode. Revision 3 of the Arduino board and the current Genuino Mega 2560 have the following improved features: 1.0 pinout: SDA and SCL pins - near to the AREF pin ...
You may also be able to disable the auto-reset by connecting a 110 ohm resistor from 5V to the reset line; see this forum thread for details. USB Overcurrent Protection The Arduino ADK has a resettable polyfuse that protects your computer's USB ports from shorts and overcurrent. Although ...
