在 Arduino 程序中，digitalWrite(LEDpin, state) 是一个函数，用于将电平写入数字引脚。该函数有两个参数：- LEDpin：数字引脚的编号。- state：布尔值，表示要写入的电平。如果 state 为 HIGH，则表示将高电平写入引脚；如果 state 为 LOW，则表示将低电平写入引脚。因此，digitalWrite(LEDpin, state...

The following Python commands will load and read data located in a directory "/data/test". Load the module and create a reader object: import digital_rf as drf do = drf.DigitalRFReader('/data/test') List channels: do.get_channels() ...
When a pin is configured as an input, you can read it with digitalRead(), which returns 0 if the pin is low, or 1 if the pin is high. The result is usually used with anifstatement to run different code depending on the voltage on the pin. ...

I'm using a Arduino Micro-Controller (MODEL: UNO). I've built a simple program to send a byte of information to a (TTL) 595 IC shift-register. Each binary digit is then transferred out each of the 8 outputs on the 595 IC to their corresponding pin out of the LED. ...
