I decided recently to set up a string of temperature sensors around our house to work out the temperature profile of different rooms. With the recent release of the Pico W, I realised that I could do this quite simply,…
During March, and for the past week as well, I’ve been working on the latest iteration of my Picorder project. This project, which has been my “go-to project” for the past 9 years (gulp!) is now running from a Raspberry…
As part of an ongoing Raspberry Pi Pico-based project, I wanted to create a thermal camera. To do this, I first of all went shopping to find what I needed. Here are the two components for this mini project: Adafruit…
As you probably know by now, I’m not a microcontroller expert. However, with the advent of microcontrollers that use MicroPython and CircuitPython, I am a lot more comfortable using them now than I used to be! However, because the Raspberry…
At the moment, I am trying to combine several different products – sensors, displays – into a project for the Raspberry Pi Pico. One of them is the Breakout Garden 11×7 Matrix from Pimoroni. I’ve chosen to use CircuitPython as…
Jeff Epler over at Adafruit has written an excellent guide to using the Pico’s PIO functionality in combination with CircuitPython. As he points out, CircuitPython sometimes interacts differently with the PIO than standard MicroPython, so this guide was necessary to…
Adafruit have produced some exceptional tutorials/guides over the years and it appears that they are doing a sterling job on new guides for the Raspberry Pi Pico. Their latest guide shows you to how to hook up a Raspberry Pi…
At the start of the Raspberry Pi Pico launch, it was only possible to program it in either C/C++ or MicroPython. A few languages are beginning to make an appearance now, including the quite exciting prospect of Rust running on…
I’m always on the lookout for cheap electronics on eBay and AliExpress. Following on from my previous tutorial on HD44780 screens, this time, I found a small OLED display. I bought one of these from eBay for less than £5 plus…
The Ruiz Brothers over at Adafruit have created a really lovely sand simulator using a Raspberry Pi Zero, an accelerometer, an RGB LED matrix display, some small items and 3D-printed parts. Philip Burgess wrote the code which “simulates physics by calculating…
