I got the inspiration behind this project by reading internet switch tutorial posted by Talha a while ago on Hackster. It was super cool and I thought what could be more wild than controlling just an LED over the internet? Controlling a real appliance maybe! So I decided to build an ESP8266 based quick circuitry, and…
This is an idea about ESP32 and TFT screen, we can combine them to realize the function of a drawing board let us draw, and plug in the SD card to realize the function of digital photo frame to display beautiful photos. Now, we add a camera on this basis, and realize a simple…
This project focuses on developing home security solution using lasers and live alert service. The security setup can only be passed (without triggering alert) using the Bolt IOT Android app and then entering the correct password. The project works using the combination of Bolt IOT module and Arduino along with Twilio providing the messaging service….
An inexpensive WiFi repeater that you can easily build at home. A single 4800mAh battery’s expected run time is about three days. The WiFi module used is an ESP8266-01 powered with a 18650 battery. By modifying the module just mentioned with an antenna it is possible to expand the range up to 200 meters. More…
If you are tired of controlling your PC cursor with a classic mouse, why not try to replicate this project? The basic idea is simple and requires very few components. The control of the mouse is entrusted to an Arduino Micro which, as we know, thanks to the ATMEGA32U4 microcontroller allows it to be recognized…
In this project we see how to build an Arduino-based capacitive kitchen timer that allows users to interact via touch input. The finished device is driven by ATMega328PU (the same microcontroller on which Arduino UNO is based). You will need a few components, but the end result will be a unique gadget that will liven…
In this project we see how to make a walkie-talkie using an ESP32; audio data is transmitted via UDP or ESP-NOW transmission. So the Walkie-Talkie will work even without a WiFi network! The system is based on an I2S microphone and an I2S amplifier, but it will work equally well with analog microphones and headphones…
In this project we see the development and construction process of a solar-powered irrigation station. This also collects atmospheric data and soil moisture and sends them in real time to the cloud for remote monitoring, also independently controlling irrigation via a drip irrigation system, in order to keep the plants happy and within an adequate…
The idea to the creator of the project was born walking at night with his dog, and noting how the temperature changes between the inhabited areas and the fields. Just to measure the temperature and humidity, he wanted to create a small and handy device to carry around on walks. There are tons of weather…
In this IoT project, we will see how to create an IoT module that allows you to turn on 4 lamps, or any other load, controllable by Google Assistant and Alexa. As you can see from the image above, the system is based on a NodeMCU that controls a 4 relay module. In the absence…
In the age of Zoom, Messenger and Snapchat calls, communication around the world has become commonplace. But what if you could go back in time and painstakingly write the message one beep at a time? With this WiFi telegraph you can do it! Not many components are needed; essential is the ESP8266 module. We decided…
In this project we will see how to build a digital scale that uses the ESP8266 microcontroller with a load cell (and its HX711 converter). The scale is able to measure weight with gram accuracy, the sensor we are using is limited to 5Kg, but you can use one for smaller or larger weights. As…
