Learn to run multiple operating systems on your Raspberry Pi.
You can have two or more systems on the same MicroSD card or USB stick, and you’ll get a nice menu when you boot up to allow you to select which one to use.
Raspberry Pi Dual Boot
Pico Oscilloscope
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!
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.
Safely using LiPo Batteries
LiPo batteries are incredible powerhouses, they have a higher power-to-weight ratio than any other type of battery.
But with all that power comes a number of safety concerns, and not following them could lead to a deadly LiPo fire.
Today we will learn how LiPo batteries work, how to charge, discharge, balance, store and dispose of them. And, just in case, we’ll see how to extinguish a LiPo fire.
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.
Arduino IDE 2.0
Introducing the new Arduino IDE 2.0 (Release Candidate 3), the improved IDE from the folks at Arduino.
In this article we will install the IDE, check out its features, and even expose a few bugs!
MyoWare Muscle Sensor
Today we will learn about electromyography by working with a MyoWare Muscle Sensor.
We’ll see how to use this device and its shields in both stand-alone mode and with an Arduino.
