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.
Use a PS3 Controller with an ESP32
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.
Measure Air Quality with Microcontrollers
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
Using GC9A01 Round LCD Modules
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.
Sound with ESP32 – I2S Protocol
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.
Using the ESP32-CAM MicroSD Card
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.
ESP NOW – Peer to Peer ESP32 Communications
ESP-NOW allows you to create a private peer-to-peer network between ESP32 and ESP8266 devices.
Today we will learn how to use ESP-NOW with a bunch of ESP32 boards. We’ll also build a remote temperature sensor, and expand it to have multiple sensors.
ESP32 WiFiManager – Easy WiFi Provisioning
Stop hard-coding wifi credentials in your ESP32 and ESP8266 sketches – use WiFiManager instead!
This easy-to-use wifi provisioning library eliminates the need to hard-code wifi information, and makes your projects portable!
Learn how to use WiFiManager and how to easily adapt your existing sketches to eliminate hard-coding forever!
