Stacking Headers for Feather - 12-pin and 16-pin female headers Product ID: 2830 These two Female Stacking Headers alone are, well, lonely. But pair them with any of our Feather boards and you're in business! What do they do? They stack. Put the headers through your Feather and then ...
if (x > 120) digitalWrite(LEDpin, HIGH);//判断x的值是不是大于120,是的话就让LEDpin这个针脚的电平成为高电平 第二种: if (x > 120) digitalWrite(LEDpin, HIGH); 第三种: if (x > 120){ digitalWrite(LEDpin, HIGH); } 第四种: if (x > 120){ digitalWrite(LEDpin1, HIGH); digitalWrite...

It also has a 3-pin connector for connecting to the Arduino or other microcontrollers. I’ll be using these modules in my MOSFET example, but you could always elect to use discrete IRF520s instead. I’ll show you both ways in the wiring diagram. Arduino with Transistors For the first ...
