The exception is the Arduino Nano’s A6 and A7 pins, which can only be used as analog inputs.pinMode(A0, OUTPUT); digitalWrite(A0, HIGH);Some pins also have additional functions which you can find in the table below:Pin numberPin nameTypeSpecial function 1 D1/TX Digital Pin Serial ...
The Arduino Nano has a number of facilities for communicating with a computer, another Arduino, or other microcontrollers. The ATmega328 provide UART TTL (5V) serial communication, which is available on digital pins 0 (RX) and 1 (TX). An FTDI FT232RL on the board channels this serial commun...

37款传感器与执行器的提法,在网络上广泛流传,其实Arduino能够兼容的传感器模块肯定是不止这37种的。鉴于本人手头积累了一些传感器和执行器模块,依照实践出真知(一定要动手做)的理念,以学习和交流为目的,这里准备逐一动手尝试系列实验,不管成功(程序走通)与否,都会记录下来—小小的进步或是搞不掂的问题,希望能够抛砖引...
The number of serial ports isn’t the only variable between boards. There are some fundamental differences in behavior, as well. Most boards based on the AVR ATmega chips, including the Uno, original Nano, and Mega, have a chip to convert the hardware serial port on the Arduino chip to ...
These are the default signal connections for the servos and buzzer for AVR Arduino boards in the examples, you can alternatively connect them to different pins if you also change the pin number. #defineLeftLeg2//left leg pin#defineRightLeg3//right leg pin#defineLeftFoot4//left foot pin#de...
