How to use String.toInt() Function with Arduino. Learn String.toInt() example code, reference, definition. Converts a valid String to an integer. If no valid conversion could be performed because the String doesn't start with a integer number, a zero is
/*GraphA simple example of communication from the Arduino board to the computer: Thevalue of analog input 0 is sent out the serial port. We call this "serial"communication because the connection appears to both the Arduino and thecomputer as a serial port, even though it may actually use a...

I2C总线的Arduino库函数 I2C即Inter-Integrated Circuit串行总线的缩写,是PHILIPS公司推出的芯片间串行传输总线。它以1根串行数据线(SDA)和1根串行时钟线(SCL)实现了双工的同步数据传输。具有接口线少,控制方式简化,器件封装形式小,通信速率较高等优点。在主
int digitalRead(pinNumber) This method reads the state of a pin that is in input mode. This can be either HIGH or LOW, that is, 5V or 0V, and no other value. The digitalRead method is used for reading buttons, switches, anything that has a simple on and off, and any control that...
