Introduction Released in 2021, the Raspberry Pi Pico has gained popularity due to its compact size, powerful capabilities and affordable price. With a dimension of just 6x20mm, the Pico harnesses the power of a dual-core microprocessor and more I/O pins in a smaller form factor. The core of the device is the RP2040 chip, developed […]

In this article, I outline my development of a smart thermostat using the Raspberry Pi single-board computer as the controller, along with a Pi Plate expansion board. The thermostat interface is web-based, allowing remote control from any device with a standard browser such as a computer, phone, or tablet. It can also be operated through […]

In this tutorial we will see how to use WhatsApp with Raspberry Pi. We will use the Yowsup library we had already used in these tutorials: WhatsApp message from Phidgets SBC , Phidgets WhatsApp – ask the status of your sensors. The library has recently undergone a complete rewrite and improvement, so we will cover […]

The article demonstrates how to use a Raspberry Pi, motor driver board, and stepper motors to control the direction, speed, and rotation of stepper motors for robotics applications. Gaining experience with basic electronic components like LEDs and switches that can be incorporated into robots helps develop the electronic and programming skills needed to interface motors […]

The Broadcom chip used in the Raspberry Pi 2 Model B The underlying architecture in BCM2836 is identical to BCM2835. The only significant difference is the removal of the ARM1176JZF-S processor and replacement with a quad-core Cortex-A7 cluster. Cortex-A7 MPCore processor   The Cortex-A7 MPCore processor is a high-performance, low-power processor that implements the ARMv7-A […]

Objective The objective of the project is to use the Raspberry Pi to create a touchscreen, and Heads Up Display (HUD) for a car. The HUD will also present other necessary real-time data about the vehicle by way of a graphical user interface on a PiTFT screen. Speed, acceleration, temperature inside the car, and rotations […]

The low-cost yet capable Raspberry Pi computer provides unique I/O options like I2C and GPIO that open new possibilities. Its standard I2C bus inspired use for model railway automation in 2013. Together with fellow hobbyist Peter Giling from the Netherlands, a range of modules have been created leveraging these capabilities for model train control and […]

Introduction IoTSyS serves as a middleware integration platform for the Internet of Things. It offers a communication stack for embedded devices utilizing IPv6, Web services, and oBIX to offer compatible interfaces for smart objects. The main goal of the IoTSyS middleware is to offer a gateway solution for current sensor and actuator systems used in […]

When I setup my Raspberry Pi server 8 months ago, one of its potential uses was for me to play with PHP and hopefully learn more about this language. I found a bit of time this week, so decided to try making a minimal PHP program to control the Pi gpio from a remote computer […]

Introduction This blog post will show how to access the GPIO of the Raspberry Pi using C++. There are two methods to achieve this. One way is to control the Raspberry Pi’s GPIO registers by hand, similar to programming a microcontroller without an OS or memory management unit (using mmap). This method’s benefit is that […]
