Arduino Analog Pins There are six pins on the Arduino Uno (shown below A0 ~ A5) that can be selected for an ADC measurement; A multiplexor feeds one of the six analogue input pins into the ADC. Use the function: analogRead(pin)

When I'm using configurePin and readVoltage for analog pins using an Arduino Leonardo board I'm getting the following errors in R2023B: "specified Key type does not exist" and "the first input must contain a multiple of 2 elements.." See code snippe...
Arduino 拥有和 C 相同的语法规范。 语法 #define 常量名 常量值 注意,#是必须的。 例子 #define ledPin 3 //在编译时,编译器将使用数值 3 取代任何用到 ledPin 的地方。 提示 在#define 声明后不能有分号。如果存在分号,编译器会抛出语义不明的错误,甚至关闭页面。 #define ledPin 3; //这是一种错误...
#define YP A2 // must be an analog pin, use "An" notation! #define XM A1 // must be an analog pin, use "An" notation! #define YM 6 // can be a digital pin #define XP 7 // can be a digital pin #define TS_MINX 150 ...
