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…
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…
In this blog we will learn how to program Raspberry Pi PICO 2 or 2W boards using Arduino IDE. For more details on Raspberry Pi PICO refer my post on the same here. Installation of Arduino IDE First step is…
Below is the Youtube video where I have shown how to repair Aquaguard UV+UF water filter PCB. The symptom was continuous blinking for all three lights in cycle. This scenario was not mentioned in the user manual. Some of the…
