Raspberry Pi Tutorial

The serial port is a common way to “talk” to devices and is a feature that most microcontrollers and computers have. This Raspberry Pi Serial tutorial teaches you how to utilize the board’s UART feature in order to connect to a PC or to other microcontrollers and peripherals.

For the next part of series on Raspberry Pi, I will show how to produce a PWM signal from a pin. Moreover, I will show you how to control single and multiple servo motors in this Raspberry Pi PWM tutorial.

The Raspberry Pi is a Linux computer. But unlike most desktop and laptop Linux computers, users have access to a row of pins which can be used as inputs or outputs. These 40 pins are called GPIO (General Purpose Input Output) pins. This Raspberry Pi GPIO tutorial aims to help …

Using RFID cards and tags is a cool way to switch on anything, wirelessly. For example, you can create an e-lock for your room, check meeting attendance or use cards to control your robot. In this tutorial, we will add RFID functions to a Raspberry Pi Zero.

The Raspberry Pi Zero W comes with both WiFi and Bluetooth connectivity. I have already covered how to turn on WiFi on my previous tutorial. Now, let’s look at how to set up a Raspberry Pi Zero bluetooth connection without a GUI.

Last year, both Raspberry Pi and Beaglebone Black released mini versions of their popular microcomputers: the Raspberry Pi Zero and PocketBeagle. I happened to own both and had a chance to compare. Which small-size single board computer (SBC) is better? It’s Raspberry Pi Zero vs. PocketBeagle after the jump.

The Raspberry Pi comes with a camera connector on board. But if you don't want to buy the official camera and use a web camera instead, you can! I'll show you how to display a video from the web cam on a web server hosted by a Raspberry Pi

I finally got my hands on a Raspberry Pi Zero W and started the usual tinkering. For those unaware, this smaller version of the Raspberry Pi packs a 1 GHz CPU and 512 MB of RAM. But what excites me the most is the WiFI and Bluetooth connectivity that comes …

In this tutorial, I will show you how to add an LCD hat to your Raspberry Pi. This is an alternative to connecting an LCD display to your Pi through its HDMI port. 

The 16x2 parallel LCD (HD44780) is a popular liquid crystal display among hobbyists due to its cheap price and ease of use. The Arduino platform recognizes its popularity and created the LiquidCrystal library for it. The Arduino LCD tutorial covers that. I attempted to port the LiquidCrystal library to the …
