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.
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.
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!
Today we will be putting together a robot car based upon the popular ESP32CAM module.
Our car will have a WiFi remote control and will stream video, so you can see where you are going when you drive it!
Simplify your ESP32-CAM experiments by building this simple developers module.
This handy accessory has a solderless breadboard, prototyping accessories, and a built-in power supply that can also be used for other projects and can run on batteries or AC.
It’s an easy build and you probably already have most of the parts.
Today we will look at a few different ways to drive a servo motor with an ESP32 microcontroller.
We’ll be using a replacement for the Arduino Servo Library and recompiling classic Arduino servo sketches to work with the ESP32.
We will also drive multiple servos with a PCA9685 PWM module and build a web-based servo motor control.
Today we will look at the amazing ESP32-CAM module from A-Thinker. This 10-dollar module features a 2MP camera, microSD card socket, WiFi, and Bluetooth.
Unlike other ESP32 modules this one does not have a USB port, so you’ll need to use an FTDI adapter to get it working.
In this article I’ll show you how to work with the ESP32-CAM and how to resolve common power and antenna issues.
