FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Let’s have a look at some examples: Pins 1 and 17 provide 3.3V power. Pins 2 and 4 provide 5V power. Pins 6, 9, 14, 25, 30, 34 and 39 are GND.

Detailed explanation-2: -The power and ground pins are used to power external circuitry. All Raspberry Pis with the standard 40 GPIO pins will have two 5V pins and two 3.3V pins, always in the same place. Along with the 5V and 3.3V pins, 8 ground pins are available.

Detailed explanation-3: -The 5v power pins are connected directly to the Raspberry Pi’s power input and we can use these pins to run low power applications. Then there are the ground pins. There are eight ground pins and all of these are connected to each other; you can use any of these ground pins for your projects.

Detailed explanation-4: -• Ground (GND): These connect to ground, to close your circuit. • DNC: This stands for “do not connect”, so don’t worry about them. • GPIO: These can be set to either send, or receive control voltages. GPIO stands for ‘General Purpose Input/Output’, and it’s these pins that let the Raspberry Pi do its magic.

Detailed explanation-5: -GPIO stands for General Purpose Input Output. The Raspberry Pi has two rows of GPIO pins, which are connections between the Raspberry Pi, and the real world. Output pins are like switches that the Raspberry Pi can turn on or off (like turning on/off a LED light). But it can also send a signal to another device.
