Looking for a power supply for your next project? How about one that can deliver up to 20 volt’s at 5 amps?
USB-PD is a technology that permits USB power supplies and chargers to deliver multiple voltages and currents. Today we wil learn how to use USB-PD in our projects.
Meet the Alvik, a tiny yet powerful robot from Arduino. Alvik may be small, but it packs some advanced sensors and can be programmed using MicroPython or C++.
Let’s take a close look at the Alvik and learn how to write code for it. We’ll also see how we can add servo motors and I2C devices to expand our robots capabilities.
Why use a mouse, keyboard and monitor with your Raspberry Pi when you don’t have to? Learn to enable and use Remote Access on the Raspberry Pi and control your little boards from anywhere in the world!
We wil examine three remote access methods you can use – SSH, VNC and Raspberry Pi Connect.
Bluetooth Classic and Bluetooth Low Energy (BLE) and short-range communications systems that connect computers, mobile devices, peripherals and sensors. You probably have several Bluetooth devices in your home, and with the ESP32 you can connect to all of them.
The ESP32 is Bluetooth-capable, but not every ESP32 wil work with every version of Bluetooth.
Join me today to learn all about Bluetooth and how to work with it on the ESP32.
The multimeter is the most essential piece of test equipment you can own. It’s ability to measure current, voltage , resistance and many more parameters makes it indispensable for the technician or experimenter.
Today we will see how to use a multimeter to measure just about everything.
Let’s build a solar camera and take pictures of the Sun! We will use a Raspberry Pi HQ Camera with a Celestron EclipSmart Solar Telescope to stream video and images of the Sun.
And if you don’t want solar pictures you can use any regular telescope and enter the wonderful universe of Raspberry Pi Astrophotography!
The Arduino IoT Cloud has had many exciting updates since we last examined it, so many that in 2024 it doesn’t even look the same! With a wealth of boards to connect to, and new features like Triggers, it’s time we took another look at the Arduino IoT Cloud.
Follow along for a detailed guide, suitable for makers of all levels!
Diodes are the oldest and most elementary semiconductor. They are also among the most useful, and there are a variety of diodes to do everything from convert AC to DC to detecting radio waves and to producing light.
Today we wil take a look at diodes. We’ll see how they work, and how to use them.
Since its introduction in 2016, the ESP32 has become one of the most popular microcontrollers in the world. It has now grown from a single ESP8266 replacement chip into a complete line of powerful microcontrollers and communications modules.
Today we will look at the status of the ESP32 as of January 2024. We will also take a look at a new Alpha of the ESP Boards Manager for the Arduino IDE.
A complete guide to the tools you need to work with electronics. Everything from screwdrivers and pliers to soldering and crimping equipment.
This guide is for experimenters, creators and service folks of all levels. Check it out and pick up a few new tools for your own workshop!
