The loop() function is called repeatedly after setup() and contains the main logic of the program. In loop(), the digital pin 22 is turned on (set to a HIGH state) using the digitalWrite() function. Then a delay of 1000 milliseconds (1 second) is introduced using the delay() function...
An ESP32 development board contains an ESP32-WROOM-32 module, made by Espressif Systems of Shangai, China. The ‘W’ in the name is silent. So, ‘WROOM’ is pronounced as ‘room’. Sadly, many on-line presenters mispronounce this chip's name, pronouncing the 'W', which should be sil...

Whereas a barcode is a machine-readable optical image that contains information specific to the labeled item, the QR code contains the data for a locator, an identifier, and web-tracking. To store data efficiently, QR codes use four standardized modes of encoding: numeric, alphanumeric, byte ...
This project is very similar to a previous one, but after many requests, we added a PIR motion sensor to the circuit. So, when motion is detected a picture is taken and saved on the microSD card.Other ESP32-CAM projects and tutorials:...
