![]() The Raspberry Pi 3 has 26 GPIO pins, the rest of the pins are power, ground, or “other”. These pins facilitate the communication of Raspberry Pi with the outside world and let it control electronics and other devices. The Raspberry Pi has 2 rows of GPIO pins which can be used to connect LEDs or can be used to send signals to other devices. Breadboard, Resistors, LEDs and jumper wiresĪ general-purpose input/output (GPIO) is an uncommitted digital signal pin on an integrated circuit or electronic circuit board whose behavior - including whether it acts as input or output - is controllable by the user at run time.I bought all the items from Amazon but you can find it anywhere.
