The Raspberry Pi can control LEDs, turning them on and off, as well as motors and other devices. It can also detect whether a switch has been pressed, as well as detect temperature and light.
As shown in the breadboard diagram at the top of the page, place the Tri-color LED on the breadboard.
Connect the red lead of the Tri-color LED to one end of the 330 resistor.
Connect the other end of the 330 resistor to the Raspberry Pi 2's Pin 29 GPIO5.
Connect a column on the breadboard to the resistor from the corresponding row on the breadboard. In the same row as the resistor, connect the LED to the cathode. Place the anode in the next row. Connect the GPIO Pin 21 (3.3 V) in the same row as the LED anode with another jumper cable.
Check that your Raspberry Pi is turned on. Take another male-to-female jumper wire and place the male end on the same side of the ravine as the resistor's second leg. Then connect the female end to the GND pin.
In theory, each GPIO output can drive one LED. You can't identify which one you have because the RPi3 and RPi1 have different numbers of outputs. You should not, however, pull more than 16mA per pin and 50mA overall. If you do, your Raspberry Pi could be destroyed.
