Once got an microSD card for your Raspberry Pi in your mailbox, you can install an operating system to run it.
Typically, we download a Raspberry Pi image and use one of the imaging software to write it to our microSD card.
When the Raspberry Pi Imager came into the picture, the download step is consolidated into a single workflow.
Given that, this is how you can use the Raspberry Pi Imager to install Raspberry Pi OS.
Ever since the Raspberry Pi first appearance, many people have been hoping to use it as a desktop computer.
When the Raspberry Pi 4B came along, we saw some upgrades that can turn those hopes into reality.
Given that, let’s look at some reasons why you will want to use a Pi 4B as a desktop computer.
As I have noted in my review on the Raspberry Pi 4 Model B, the Pi 4B came with substantial upgrades.
Since it has faster (and more) RAM along with better graphics processing capabilities, the Pi 4B is well suited for multimedia deployments.
Given that, you may want to add the Raspberry Pi Official 7 Inch Touch Screen to your Pi 4B so that you can use it to build a kiosk.
If that’s the case, read on to see how to setup the Raspberry Pi Official 7 Inch Touch Screen with your Raspberry Pi 4B.
Many useful applications are written in PHP backed by MariaDB/MySQL for data persistency.
When you wondering what you can use a Raspberry Pi for, one way is to turn it into a LEMP server for hosting PHP applications.
With this in mind, let us look at how we can setup a Raspberry Pi LEMP server with Raspbian Buster Lite for running PHP applications.
When you deploy multiple Raspberry Pis in your house, it is a good practice to give each of them a unique hostname. Since the default hostname for Raspbian is raspberrypi, it will be easier to look for the IP address of a new Raspbian installation in this situation.
Given that, let us look at how you can change the hostname of your Raspberry Pi in Raspbian via the Raspberry Pi Software Configuration Tool (raspi-config).
When I did a Raspberry Pi 4 Model B review, I got myself a Raspberry Pi 4 Model B. Therefore, the current Raspberry Pi 3 Model B+ that I have been using for validating Raspberry Pi ideas became available for another IoT project in the house.
So what should I do with my Raspberry Pi?
Since I have always wanted to build my own indoor herb garden, I plan to use it to help my plants grow well.
When I bought the LED Grow Lights, I am able to give my plants consistent lighting. Given that consistent lighting is solved, I can use my Raspberry Pi 3 to monitor soil moisture so that I can provide water my plants better.
Given these points, this is a proof of concept that I did to read soil moisture level with my Raspberry Pi and a YL-69/FC-28 moisture sensor.
Although your Raspberry Pi is unable to read analog input out of the box, you can get a MCP3008 I/P ADC chip to help your Raspberry Pi do so.
When you connect a MCP3008 I/P chip to your Raspberry Pi, you can read up to 8 analog inputs with SPI.
Given these points, this post will show you how you can use the MCP3008 I/P chip to help your Raspberry Pi read digital data from analog sensors.
Your Raspberry Pi has the ability to communicate with hardware using the Serial Peripheral Interface specification. However, this master driver is disabled by default.
If you want to use the SPI master driver to communicate with devices, then you will need to enable it.
Let’s look at how we can enable the SPI master driver using the Raspberry Pi Software Configuration Tool (raspi-config).
Whenever I am working on a Python 3 project, I will always use a Python 3 virtual environment for running that project. Therefore, I tend to do the same when it comes to .
If you are looking to build Python 3 applications to run on your Pi, then you may find this article useful for you.
