A complete guide to using DC servo motors with microcontrollers like Arduino and ESP32.
Learn how servos work, how to code for them and get some troubleshooting tips.
DC Servo Motor Guide – With ESP32 & Arduino
ESP32 Boards Manager 3 – Updating Your Old Code
ESP32 Boards Manager 3 for the Arduino IDE offers a significant improvement over previous versions. But that improvement comes at a cost – a lot of older ESP32 code will no longer compile.
Today we wil examine the new features of Boards Manager 3 and see how to convert our older code.
ESP32 Guide 2024 – Choosing and Using an ESP32
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.
IR Remotes Revisited – 2023
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.
Seeeduino XIAO ESP32S3 Sense Board – A Tiny ESP32 Camera
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
ESP32-CAM Object Detection with Edge Impulse
Object Detection used to require huge computing resources, but that has all changed. Using the power of Edge Impulse, you can train an object detection model that will run on an inexpensive ESP32-CAM board.
This article will show you all the steps you need to take, from taking images of your objects to training them with a neural network. And it’s really easy too!
Use a PS3 Controller with an ESP32
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.
Using ChatGPT to Write Code for Arduino and ESP32
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!
Using the ESP32 DAC (and making a Fruity Instrument)
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 Wheel Robot Car with ESP-NOW Remote Control
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.
