The Uno is a microcontroller board based on the ATmega328P. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header and a reset button. Revision 3of the board has the ...
We know that an arguing Uno R3 includes 14-digital pins which can be used as an input otherwise output by using the functions like pin Mode (), digital Read(), and digital Write(). These pins can operate with 5V, and every digital pin can give or receive 20mA, & includes a 20k to...
例如,Arduino以太网扩展板使用引脚10控制到板载SD卡的SPI连接,并使用引脚10控制到以太网控制器的连接。 库函数 两块UNO开发板通过SPI通讯 两块Arduino UNO R3开发板通过SPI进行通讯,则需要其中一块作为主设备,另外一块(或多块)作为从设备,同时两块开发板需要共地连接,引脚接线方式如下: UNO(主) UNO(从) (MOSI)...

The Arduino UNO R3 is the perfect board to get familiar with electronics and coding. This versatile microcontroller is equipped with the well-known ATmega328P and the ATMega 16U2 Processor.This board will give you a great first experience within the world of Arduino.Target areas:Maker, ...
This GPS shield works great with any "Arduino shaped" board that has SPI and UART pins available, and is designed to log data to an SD card. Or you can leave the SD card out and use the GPS for a geocaching project, or maybe a... Add to Cart, Adafruit Ultimate GPS Logger ...

也正因为次,在 Arduino 的官方指南中提到,“The analog input pins can be used as digital pins, referred to as A0, A1, etc. ”。说的是,模拟输入口可以当数字口一样用。对于A0-A5来说,确实不错。但对于第一功能就是ADC(模数转换)而不兼有普通 IO 口功能的 ADC6 和 ADC7 来说。这句话就要打...
