In this getting started tutorial, we will learn to interface the DRV8825 stepper motor driver module with ESP32. This DRV8825 driver module which is used to control a stepper motor in a relatively simple manner. Using only two pins of the ESP32 and DRV8825 driver module, we can control the speed of the rotation as … Read more
This ESP32-CAM guide shows an easy way to capture photos through ESP32-CAM and upload or store them to Google Firebase storage. Firstly, we will create a Firebase project to store photos or any files. The Firebase project data will be secured by enabling email/password authentication as well. Hence, the photos captured by ESP32-CAM and uploaded … Read more
This ESP32-CAM guide shows the users an easy way to capture photos through ESP32-CAM and save it to microSD card. In order to save battery, ESP32-CAM will remain in sleep mode for most of the time and wake up from deep sleep whenever the RST button will be pressed. After wake up from deep sleep, … Read more
In this project, we will create an ESP32-CAM Photo Web Server. The Web server will present the user with three options: to capture a photo, rotate the photo, and refresh the page. After capturing the photo, the photo will get saved in the ESP32-CAM’s SPIFFS files and will be fetched from the filesystem. The web … Read more
In this user guide, we will learn how to incorporate Wi-Fi manager with ESP32 Web Server projects using an AsyncWebServer library. Wi-Fi manager allows us to connect ESP32 to a network without having to hardcode our network credentials in an Arduino sketch. We will be using a previous example when we learned how to build … Read more
In this user guide, we will learn how to control a stepper motor using L298N Motor Driver with ESP32 and Arduino IDE. This is a quick guide where we will learn how to interface an L298N motor driver with ESP32 board and eventually learn how to control bipolar stepper motors in our case NEMA 17 … Read more
In this tutorial, we will learn how to interface RFID reader RDM6300 or RDM630 with ESP32 development board. Both of these RFID readers communicate via a serial connection on UART and follow the same interfacing with ESP32 thus this tutorial will be compatible with both types of RFID readers. First, we will give you a … Read more
In this tutorial, we will learn to interface L298N Motor Driver with ESP32. This is an in-depth guide about the L298N motor driver including its specifications, pinout, interfacing with ESP32 board. Firstly, we will see an example to control DC motor speed. In the end, we will see an example to control the direction of … Read more
In this tutorial, we will learn to interface MAX7219 LED Dot matrix display with ESP32 development board. Firstly, we will look into the introduction, pinout of MAX7219 LED dot matrix display module. It is an LED array used to display various types of texts, symbols, and images in the form of dots which consists of … Read more
This guide focuses on the 4 digit 7 segment display and its interfacing with ESP32 using 74HC595 shift register. By using the 74HC595 shift register to drive 7-segment displays with our ESP boards, we can save GPIO pins of ESP32. First, we will show you some descriptions of 7 segment displays and 74HC595 IC and … Read more
