Operational Amplifiers, or “op-amps”, are fundamental analog electronics building blocks that are used in both analog and digital designs. And if you are not using them, it’s about time you started!
Op-amps can be wired in dozens of different configurations, they are very versatile.< /p>
Let’s learn more about using Operational Amplifiers.
The new Arduino GIGA is the most powerful microcontroller that Arduino has ever produced.
Today we will take a first look at this monster, which has the same form factor as the Arduino Mega.
Of course, we’ll test out some of the more unique features of this board as well.
Learn to use a PlayStation 3 controller with an ESP32, and control pretty well anything!
We’ll pair an inexpensive game controller with an ESP32 and control LEDs, motors and a lot more.
ChatGPT is an amazing AI chatbot that can also generate code in just about any programming language!
Today we will see how to write both C++ and MicroPython code for Arduino and ESP32 using ChatGPT.
Put the power of an AI-assisted coder to work for you today!
Today, we will learn how to use the DAC, or Digital to Analog Converter, in the ESP32.
I’ll show you how to produce voltages and waveforms using the DAC and the Arduino IDE.
We will also make some oscilloscope “art” and even a “fruity” musical instrument!
Mecanum Wheels are unique wheels that allow you to propel a vehicle in any direction. Not just forward and backward, but sideways and diagonally as well.
Today, we will build a robot car that uses Mecanum Wheels. Our vehicle will also have a remote control with a joystick, a TFT display, and a rechargeable battery.
Learn to use seven different DC motor drivers with an Arduino Uno.
We’ll see how to put these to use with motors of all sizes, and of course we have hookup diagrams and code samples!
Measure the quality of the air you are breathing using a variety of sensors, an Arduino and an ESP32.
In this article I’ll discuss air quality parameters and show you how to use several popular sensors to measure the gases and particulate matter in the air
Learn to program the new Raspberry Pi Pico without microPython. Use the Arduino IDE and C++ instead.
In this article, I’ll show you how to install a boards manager and use it to program the new Pico W. I’ll focus on its most important feature – WiFi!
Get the best of both worlds by building a dual-boot workstation!
I’ll show you how to take a “bare-bones” workstation and install both Microsoft Windows 11 and Ubuntu Linux 22.04.
