树莓派3b板上有两个LED, pwr (power) 和 act (activity)。是platform_driver gpio-led驱动。 可以通过设备树和gpio-led来额外控制一个LED。如下图在P25和GND之间接入一个发光二极管。 在设备树bcm2710-rpi-3-b.dts中添加一个LED2来控制外部的LED &leds { act_led: act { label ="led0"; linux,default...

Arduino as LED driver LEDs can be directly interfaced with the Arduino pins. Arduino GPIO can drive an LED by either sourcing or sinking current through it. However, as the LED must be controlled by the Arduino pin, the pin must be configured as a digital output. ...
