Typecasting in Arduino programming is another way of converting one data type to another. In Arduino, typecasting from int to float is done by placing the data type you want to convert to in parentheses in front of the variable that you want to convert. Here’s an example: int myInt =1...
// convert ADC value to voltage float Vin = 5 * sensorValue / 1023;// print out the value you read:Serial.println(Vin);delay(1); // delay in between reads for stability } 逐行分析，这段代码有如下作用：Serial.begin(9600);指示电路板与电脑之间开始9600比特每秒的串行通信 float sensorV...
