Learn how to use both 7-segment and dot-matrix LED displays with an Arduino.
We will be working with both single and multiple display units, in a variety of configurations.
LEDs are by no means dead, they are still a great choice for a number of applications. Add one to your next Arduino project.
In addition, we will build an Arduino OLED Temperature and Humidity Meter using an OLED and an I2C temperature and humidity sensor.
RGB (Red-Green-Blue) LEDs are versatile devices that can add color and functionality to your Arduino projects.
In this article we’ll examine the different types or RGB LEDs available to experimenters and see how to best use them with an Arduino. It promises to be a very colorful read!
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!
The Arduino GIGA Display Shield is a powerful TFT display with integrated IMU, microphone and RGB LED. This capacitive touchscreen display even has a connector for a camera.
Today we will see how to use this display and its advanced features to build powerful user interfaces.
