In this project, we are building an ESP32-based GPS Data Logger using the NEO-7M GPS module and a microSD card. The goal is to capture GPS information such as latitude, longitude, speed, date, time, and satellite count, and save the…
In Episode 6 of the ESP32 Portable WiFi Scanner project, we take the project one step further by adding battery monitoring. The scanner is designed to run as a portable device using an 18650 Li-ion battery, so being able to…
Introduction Welcome to Episode 2 of the ESP32 Wi-Fi Scanner Project. In Episode 1, we built a basic Wi-Fi scanner that displayed nearby Wi-Fi networks on the Serial Monitor. In this episode, we’ll take the project to the next level…
For this project we will be using a ESP32 with 16×2 I2C LCD display, but LCDs with other sizes should also work. The advantage of using an I2C LCD is that the wiring is really simple. You just need to…
This is in continuation to my earlier post on ESP32 Digital Clock using TM1637. Here we will see on how to build ESP32 Weather Clock with TM1637 Display using Weather API. We will use weather API to get local temperature…
In this post we will Learn how to build a real-time ESP32 digital clock using a TM1637 4-digit display and NTP time sync. This tutorial covers complete wiring, Arduino code, WiFi setup, and troubleshooting common issues like ESP32 reset and…
What is an ESP32? The ESP32 is a series of chip microcontrollers developed by Espressif. It is a low cost which makes it easily accessible to the general public. The ESP32 consumes very little power compared with other microcontrollers, and…
