It’s time we took a fresh look at infrared remote controls, so here is everything you need to know about using IR remote controls with microcontrollers.
Learn how to receive, decode and send IR signals, including ones from those hard-to-decode remotes like air conditioners.
Examples with both an Arduino and ESP32.
The Seeeduino XIAO ESP32s3 Sense board is a super-tiny ESP32 camera board that includes a microphone, MicroSD card, USB-C connector and a battery charger.
Today we will take a look at this tiny microcontroller and put it through the paces. We’ll also upgrade its camera and build a camera that also records sound
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.
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
The GC9A01 is a circular LCD module that is ideal for instrumentation and other cool display applications.
In this article, we will learn how to use this display with an Arduino Uno and an ESP32.
The I2S protocol is not a misspelling of I2C, it is a protocol for controlling digital audio.
Today we will use the I2S protocol and some I2S peripherals with an ESP32. We’ll display microphone waveforms and build an MP3 player and an Internet Radio.
Learn how to use one of the ESP32-CAM board’s most neglected features – the MicroSD card. In this article, I’ll show you how to use the MicroSD card to store photos taken with the camera.
We will also build a motion-sensitive and a time-lapse camera using the ESP32-CAM.
