In this project, I’ll show you how you can build your own mood light. You’ll use an ESP8266 to remotely control the color of your light using your smartphone or any other device that has a browser. More info
https://youtu.be/Sn2sbEnmoYk In this project I have designed a remote WiFi Controlled Audio Source Selector Switch (Wi-CASSS) with a ESP8266 board which enables the user switch between two connected input/output audio devices over internet. Hence this removes the difficulty of swapping in the audio cables every time one connects a new device. More info
Often when designing Data acquisition systems, such as plant health monitoring in which case, the sensors are placed on-site, knowing the weather conditions may help in predicting the behaviour of other data and changes in physical requirements, if any. The project involves the design of an IoT based solution to monitor the data obtained from…
This tutorial shows how to detect motion with the ESP32 using a PIR motion sensor. In this example, when motion is detected (an interrupt is triggered), the ESP32 starts a timer and turns an LED on for a predefined number of seconds. When the timer finishes counting down, the LED is automatically turned off. More…
Using a relay with the ESP32 is a great way to control AC household appliances remotely. This tutorial explains how to control a relay module with the ESP32. We’ll take a look at how a relay module works, how to connect the relay to the ESP32 and build a web server to control a…
In this project, you’ll build a sensor monitoring system using a TTGO LoRa32 SX1276 OLED board that sends temperature, humidity and pressure readings via LoRa radio to an ESP32 LoRa receiver. The receiver displays the latest sensor readings on a web server. More info
In this tutorial we will learn how to program ESP32 M5Stack StickC with Arduino IDE and Visuino to Display a time on the LCD and also set the time and the brightness using the menu and the StickC buttons. More info Try Fishino boards, our 100% Arduino compatible boards.
There is no question that ESP32 is a worthy competitor to many WiFi/MCU SoCs out there, often beating it on both performance and price. But, depending on which state it’s in, the ESP32 can be a relatively power-hungry device. When your IoT project is powered by a plug in the wall, you tend not to care…
To ensure the security and remote access we want to think of a new way to connect our door lock to our personal devices. Let’s think about our mobile phones, they have the capability to control our smart door locks through MQTT and available protocols. Then why don’t we add an additional biometric firewall to…
Every once in a while you’ll come across an idea where keeping time a prime concern. For example, imagine a relay that has to be activated at a certain time or a data logger that has to store values at precise intervals. The first thing that comes in your mind is to use…
A fantastic feature of any WiFi-enabled microcontroller like ESP8266 NodeMCU is the ability to update its firmware wirelessly. This is known as Over-The-Air (OTA) programming. More info
In this project, I will guide you on how to build a basic mobile phone using the STM32F407 Discovery Kit and GSM A6 module. This project contains 3 main modules : GSM A6 Module – This is module is responsible for Making/Receiving Calls and SMS. LCD 16×02 Display – To see the output Hex Keypad…
