Random Nerd Tutorials (RNT) is a website and an online community, run by two siblings from Portugal, Sara and Rui Santos, who help makers, hobbyists and engineers build electronics projects. Since its establishment in 2013, RNT has become a trusted place to learn electronics and programming online, providing more than 200 free tutorials published online, which anyone can follow. A number of these project tutorials, courses and guides are focused on ESP32 and ESP8266.

ESP32

• Programming the ESP32 with Arduino IDE (course)
• ESP32 blog posts and projects

ESP8266

• Home Automation Using ESP8266 (course)
• ESP8266 blog posts and projects

Recently, Rui Santos posted a really interesting blog entry which demonstrated how to build a web server with the ESP32-CAM board that allows sending a command to take a photo and visualizing the latest captured photo in your browser, having saved it first in SPIFFS. He also added the option of rotating this photo, if necessary, as well as a video demonstration of what can be built throughout this tutorial.

Readers take the ESP32-CAM project further, by adding a PIR sensor to take a photo when motion is detected, a physical pushbutton to take a photo, or also include video streaming capabilities in another URL path. RNT have several exciting ESP32-CAM projects in their blog. These include:

• ESP32-CAM PIR Motion Detector with Photo Capture (saves to microSD card)
• ESP32-CAM Video Streaming and Face Recognition with Arduino IDE
• ESP32-CAM Video Streaming Web Server (Home Assistant, Node-RED, etc.)
• ESP32-CAM Take Photo and Save to MicroSD Card
• ESP32-CAM Troubleshooting Guide
