In this ESP32-CAM tutorial, we will use machine learning techniques to build an image classification project using ESP32 CAM. The ESP32-CAM will be used to capture an image which will then be identified using a trained Machine learning model. For this project, we will use Clarifai’s image recognition AI models. Recommended Components The following components … Read more
In this user guide, we will learn to build ESP32 Gauges Web server using Server-Sent Events (SSE). Using this technique, we will build an ESP32 controlled web server that will automatically update sensor readings such as temperature and humidity to all connected web clients and display them in linear and radial gauges. Any appropriate sensor … Read more
In this getting started tutorial, we will learn to interface the A4988 stepper motor driver module with ESP8266 NodeMCU. This A4988 driver module which is used to control a stepper motor in a relatively simple manner. Using only two pins of ESP8266 NodeMCU and A4988 driver module, we can control the speed of the rotation … Read more
