If you like Raspberry Pi & Python, want to make AWESOME DIY Hardware Projects then this guide is for you
Using Python you can program all aspects of the Raspberry Pi hardware and make it talk to different peripherals, sensors and actuators and build realistic projects
Take your pick from the listed hardware interfaces below and explore the tutorials
Each tutorial contains accompanying demo assets consisting of hardware schematic, source code, and configuration steps that are easy to follow. You can complete it in no more than one hour.
Before You Start
Make sure you have the following hardware at your disposal
Additionally, you will also need the following passive components and accessories to make the circuits (You can purchase an all inclusive electronics kit* containing all the items).

GPIO is the most commonly used interfaces used in Raspberry Pi. Although the Raspberry Pi GPIO pins can be programmed for multiple different hardware, protocols, this tutorial focuses on using the GPIO pins as basic digital output to glow an LED. But how do you trigger the LED? You will learn about a way to trigger the LED externally via a web browser.
Like the digital, there are many applications that require analog inputs. Raspberry Pi does not have an inbuilt support for capturing analog signals. In this tutorial you will learn how to use Raspberry Pi in conjunction with an Analog to Digital Convertor (ADC) to capture analog signals and visualize them on a chart.
Pulse Width Modulation is a technique to vary the width of a digital square wave signal. It has some specific applications and is widely supported across different hardware chipsets. Raspberry Pi also supports PWM by default and this tutorial will show you one of the ways in which you can leverage PWM in your hardware projects.
I2C is a standard protocol used for communicating across multiple masters and slave hardware peripherals. Many sensors support this as their default interface for connecting with the controller. Raspberry Pi has support for the I2C interface and this tutorial will show you how to setup I2C interface in it for exchanging data with two Arduino UNOs acting as I2C slaves.
UART is a very common hardware interface. Most communication peripherals support UART and it is easy to setup and use. This tutorial will provide you all that you need to know for configuring a Raspberry Pi as a UART master device and communicate with Arduino UNO that acts as a slave device.
Like I2C, SPI is also another popular hardware interface that enables Raspberry Pi to communicate with multiple slave devices. In this tutorial you will learn about the basics of SPI interface, and how to setup Raspberry Pi as SPI master, that can communicate with two Arduino UNOs as SPI slaves.
Here is a bonus for you. Raspberry Pi also has inbuilt support for audio. So why not make a cool demo application that converts Raspberry Pi into an audio broadcasting service. Check out this tutorial to learn more.
