In this guide we will be showing you how to enable support for the SPI protocol on your Raspberry Pi. SPI is a synchronous serial interface for communicating with other devices. You can send and read data from the connected devices.
In this guide, you will be learning how to configure your Raspberry Pi to connect to devices over the I2C interface. The I2C interface is a unique method for two chips to be able to communicate with each other synchronously.
This comprehensive guide walks you through the GPIO pinout of the various Raspberry Pi’s. This guide will provide you with an easy way to see what each of the GPIO pins can be used for with simple diagrams.
This tutorial takes you through the process of connecting an APA102 RGB LED strip to the Raspberry Pi. We also build a simple Python script that can be used to control the LED strip. It’s an excellent tutorial and great for learning the basics of using the LEDs.
This tutorial takes you through all you need to know for setting up a UV sensor with the Raspberry Pi. We also build a simple Python script that will retrieve the UV index from the VEML6075 UV sensor. It’s a simple project and great if you want to monitor UV levels.
This tutorial will take you through all the steps to setting up an accelerometer with the Raspberry Pi. We go through the circuitry and the Python code that you need to bring it all to life. We make use of the ADXL345 sensor, but others may work as well.
In this tutorial, we take you through the steps of connecting a humidity sensor to the Raspberry Pi. We also do some basic Python coding so that we can communicate with the sensor. It’s an excellent tutorial if you wish to collect humidity and temperature.
In this project, we take you through all the steps to set up an attendance system that makes use of the RC522 RFID reader. It is quite a long tutorial, but we cover everything from setting up the RFID reader right through to an MYSQL database and a web frontend.
In this tutorial, we will be showing you how you can set up a Raspberry Pi Sense HAT digital clock by utilizing its LED matrix. Throughout the tutorial we will be showing you how to write a script on your Raspberry Pi that can grab the current system time and then interpret that into something […]
In this Raspberry Pi pressure pad tutorial, I will go through the steps of connecting a force sensitive resistor to the Pi. There are many uses for a pressure pad, such as detecting when someone sits down or places pressure on a specific part of an object. It is a pretty great sensor to make […]
In this Raspberry Pi distance sensor tutorial, we will be utilizing the HC-SR04 Ultrasonic Sensor with our Raspberry Pi. This guide will go through showing you how to wire up the sensor with the Raspberry Pi as well as exploring how we can utilize the sensor also to read distance. We will be showing you […]
In this Raspberry Pi RTC tutorial, we will be showing you how to add either the PCF8523, DSL1307 or DS3231 real-time clock (RTC) modules to your Raspberry Pi. We will be showing you how each of the individual real-time clock chips needs to be wired up to the Raspberry Pi to function correctly by providing […]
In this Raspberry Pi serial reading and writing tutorial, we will be showing you how to read and write data through the serial GPIO connections that are made available to you on your Raspberry Pi. We will be showing you how to do these serial writes by using an RS232 to TTL Adapter to create […]
In this Raspberry Pi RFID RC522 tutorial, I will be walking you through the steps on how to set up and wire the RFID RC522 chip with your Raspberry Pi. This project is a cool circuit to play around with and opens you up to quite a wide variety of different projects from using it […]
In this tutorial, I go through the steps of setting up a Raspberry Pi ADC (Analog to digital converter). As you may already know the Pi doesn’t have any GPIO pins that are analog. This lack of analog pins makes connecting analog sensors a little more complex. There are several solutions to the lack of […]
In this tutorial, I will be looking at how to set up Raspberry Pi cayenne. This tutorial is a pretty simple process and will give you access to a powerful IoT software package. If you’re a fan of sensors, collecting data and the overall concept of IoT then this is for you. There are quite […]
In this tutorial, we take you through the steps of connecting a DS18B20 temperature sensor to the Raspberry Pi. This is an excellent way of collecting the temperature of the air, nearby liquid or anything else you want to know how hot or cold it is.
In this Raspberry Pi light sensor tutorial, I show you how to connect the photoresistor sensor up to the GPIO pins correctly. Lastly, I show you how it can be used in a simple python script, so you’re able to gather and use the data from it. This photoresistor is yet another sensor that I […]
This tutorial dives into the process of building a motion detecting circuit using a PIR sensor. We go one step further and integrate a buzzer, so every time motion is detected you will get a beep. It’s the perfect tutorial for learning some basics to electronics.
