Build a small oscilloscope using a Raspberry Pi Pico and your Android phone or tablet.
The Scoppy Android app makes it all possible. It will even function as an 8-channel logic analyzer!
Pico Oscilloscope
Raspberry Pi Standby Switch
The Raspberry Pi is a great microcomputer, but it is missing one essential component – a power switch.
Learn how to wire a pushbutton to your Raspberry Pi GPIO and use it to power your Pi on and off.
NeoPixel with Pico PIO
Learn about the Raspberry Pi Pico PIO (Programmable Input/Output) feature.
We will use the PIO capability of the RP2040 microcontroller to make beautiful displays on a NeoPixel LED ring.
Raspberry Pi Network Boot
Learn to use the Network Boot feature, in beta for the Raspberry Pi 4.
This will allow you to insert a blank MicroSD card or USB stick into your Pi 4 and install the operating system over the internet.
e-Paper with Arduino & Raspberry Pi
e-Paper displays have a number of unique features, such as being visible in broad daylight, consuming very little current, and retaining their image when powered down. But they also have some disadvantages – they have poor refresh rates, limited color capability, and are more expensive than other display types.
in some applications, however, e-Paper is a perfect choice, and today we will see how to use these displays with both an Arduino and Raspberry Pi.
Raspberry Pi Autofocus Camera & libcamera
Today we will take a look at a new camera from Arducam, one that is capable of autofocus.
We will also learn to use libcamera, the new camera stack for the Raspberry Pi that replaces the older raspistill and raspivid.
This new camera is really quite a performer, yet it costs the same as the standard version 2 module.
Using GPS Modules with Arduino & Raspberry Pi
Learn to use common GPS positioning modules in your Arduino and Raspberry Pi projects.
Today we will see how satellite positioning systems work, and how to use GPS modules in our projects.
We’ll also build a GPS Logger to track our movements, then display our data on Google Maps.
Raspberry Pi Pico with CircuitPython
CircuitPython is an easy-to-use language with hundreds of libraries for microcontrollers. Today we will be using CircuitPython with the Raspberry Pi Pico
With over 300 libraries already to go CircuitPython makes it easy to expose the power of the Raspberry Pi Pico.
Today we’ll see how to install CircuitPython and how to use it to build a keyboard emulator, a mouse emulator, work with MicroSD cards and flash some addressable RGB lights.
Raspberry Pi Pico – How to Interface (almost) Everything!
The new Raspberry Pi Pico is a microcontroller – yes a microcontroller, not a microcomputer! It lists for four dollars and it uses a new MCU designed by Raspberry Pi.
To test one out I hooked up a bunch of I/O components and used MicroPython to code them.
Raspberry Pi Cameras – the BIG Picture
The built-in CSI camera connector is one of the great features of the Raspberry Pi. Adding video capabilities can really bring your project up to the next level.
Today we will take a detailed look at the Raspberry Pi Camera. We’ll see how it works, how to use it and we’ll compare different models to see which one looks best.
