The Raspberry Pi is able to control LEDs, turning them on or off, or motors, or many other things. It is also able to detect whether a switch has been pressed, or temperature, or light. In the CamJam EduKit you will learn to control LEDs and a buzzer, and detect when a button has been pressed.
Red and green lights are used to show different functions. A flashing green LED light indicates that a program is running; meanwhile, a flicker displays how the program is functioning. Red LED lights indicate whether or not the Raspberry Pi is receiving enough power.
Make sure that your Raspberry Pi is powered on. Take another male-to-female jumper wire and push the male end into the same row as the resistor's second leg, on the same side of the ravine. Then push the female end onto your GND pin. Your LED should light up!
I would like to turn off the leds of my Raspberry Pi.
I tried modifying the file echo none >/sys/class/leds/led0/trigger but nothing changed.
Is this possible?
