Complete Practical Guide of Fixing Raspberry Pi 4 Pins
by Pristine Collon Professional Writer
The Raspberry Pi 4 board has a 40-pin GPIO header. This GPIO header is also shared by Raspberry Pi 3 boards, so this guide applies to both. GPIOs enables you to use hardware features and communicate with a computer the Raspberry Pi microprocessor directly from a computer. It brings the Raspberry Pi 4 closer to hardware applications. In this comprehensive Raspberry Pi 4 pins guide, you will break down all of the GPIO header's pins and explain what you can and cannot fix with them. Along the way, you will make some comparisons with the Arduino board's pins. You'll notice that the pins for some functions are quite similar.
A word of caution
Before you connect anything to a Raspberry Pi Analog Inputs, you should be aware that you can easily damage the board if you make a mistake. If it comes to the Raspberry Pi hardware pins, there is no real hardware safety. If you directly connect a ground (GND) pin to a 3.3V pin, well. The moment those pins are connected, you risk destroying your Raspberry Pi board.
So, be extremely cautious when plugging something in or creating a test circuit. If you have any doubts, double-check and seek assistance before you burn your board. But, if you follow a few simple rules and use common sense, you will have nothing to worry about.
Ground pins
The ground is extremely useful for creating a common reference point for all of your circuit components. Remember always to connect all components to the ground. When connecting two circuits, add a wire between both grounds to make it common. When adding a new sensor or actuator to an existing circuit, connect the component's ground to the circuit's ground.
That is extremely important. Without it, you risk burning some parts of the circuit, having components that do not function properly or give incorrect values, and so on.
GPIOs are digital pins
The GPIOs on the Raspberry Pi Analog Outputs are very similar to digital pins on an Arduino board. You need to decide whether you want to use them as input or output. When you configure a GPIO as an input, you can read a value from it: HIGH or LOW (1 or 0). Also, if you configure a GPIO as an output, you will be able to write a value to it, which can be HIGH or LOW.
Power pins
There are two pins that provide 3.3V and two pins that provide 5V. These pins can power components like sensors or small actuators. It should be noted that they are in no way powerful enough to actuate motors such as servo or stepper motors. You'll need an external power source for that. The power pins are used for external power components, not to power the Raspberry Pi from a separate source. There is a chance to power the Raspberry Pi from the GPIO header, but you risk burning it, so just use the micro USB port.
The bottom line
You need to consider the above things, which can help you to fix them correctly. You should spend some time following the above particle guide to stay away from certain damages.
