How to Use Arduino Measure Voltage

/* ReadAnalogVoltage Reads an analog input on pin 0, converts it to voltage, and prints the result to the serial monitor. Attach the center pin of a potentiometer to pin A0, and the outside pins to +5V and ground. This example code is in the public domain. */ // the...

Arduino I2C 总线教程

Wire Library This library allows you to communicate with I2C / TWI devices. On the Arduino boards with the R3 layout (1.0 pinout), the SDA (data line) and SCL (clock line) are on the pin headers close to the AREF pin. The Arduino Due has two I2C / TWI...

Arduino SPI 精华课程

本章我们将深入学习 SPI 在 Arduino 硬件和开发环境中是如何工作和应用的,将使用 Arduino Uno 作为标准开发板,你可以使用其他型号的 Arduino 开发板。、 SPI 被用来从一个处理器发送、接收串行数据到另一个处理器,或者另一个外设,如 LCD 液晶屏,温度传感器,SD记忆卡等等。 更多关于 SPI 信息,请查看 Wiki http://en.wikipedia.org/wiki/Serial_Peripheral_Interface_Bus 如需了解更多 Arduino 官方对 SPI 描述,请查看...
