Project objective In this project, we build a simple magnetic door/window alarm using: The magnet activates the reed switch, which turns ON the transistor. The transistor then switches both the buzzer and LED. Circuit Diagram In version 2 we invert…
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…
In the previous episode, we expanded our ESP32 WiFi Scanner by adding BLE scanning and battery/power support. In this episode, we take the project one step further by introducing a touchscreen-based navigation system. The goal of EP5 is to transform…
In the previous episodes of the ESP32 Portable Wi-Fi Scanner project, we built the project step by step. In Episode 1, we created a basic Wi-Fi scanner that displayed nearby networks on the Serial Monitor. In Episode 2, we added…
In Episode 1, we built a basic ESP32 Wi-Fi scanner and displayed nearby Wi-Fi networks on the Serial Monitor. In Episode 2, we moved toward a graphical interface by setting up a 2.8-inch TFT display based on the ST7789 controller.…
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…
WiFi is everywhere around us. Have you ever wondered how many WiFi networks are available nearby and what information they broadcast? In this project, we’ll build a simple WiFi Scanner using an ESP32 development board and Arduino IDE. This is…
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…
