This IoT home automation project allows you to have full control of your blinds from anywhere with the use of a photoresistor, a motor and a smartphone, you can adjust the blinds without actually having to get up. As for the assembly it is necessary to insert the servo in the curtains in order to…
In this project we see how to make a lamp that can change its colour according to the environment, using the Arduino Nano microcontroller. We must therefore create an electronic circuit that takes a color as input and outputs the relative light. The most important material in this project is the TCS34725 RGB sensor (another…
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 smart bin. The system detects if the bin is already full and opens automatically when someone approaches. What gives it an edge over other smart garbage cans on the market is that it uses a touch screen display that allows the user to interact and…
In this project we transform the M5StickC board into a laser rangefinder to accurately measure distances up to 2 meters. For this we need the ToF HAT (Time-of-Flight) sensor together with the M5StickC. In addition to displaying the distance, the software can also transmit the measured value to other devices via Bluetooth. In this way,…
In this project we will see how to make a thermometer to measure the temperature in the room with a measuring range from 10 degrees to 35 degrees Celsius and an accuracy of 0.5 degrees. The temperature is displayed on the WS2812 LED bar containing 50 diodes. Characteristic of this thermometer is that in addition…
A challenge faced by many hospitals, especially during the current times, is the understaffing and the inability to constantly monitor each patient at the same time. This system can alert hospital staff that a patient in a wheelchair may have problems by monitoring the chair’s actions using three sensors (an obstacle detection module, a tilt…
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…
In this project we see how to build an IOT-based dust monitoring system that can measure surrounding dust, send data over the Internet, and monitor the long-term value graphically. We use a Sharp gp2y1014au0f particle sensor which uses an IR LED and when the particle enters the sensor, the light bounces back to a photodetector….
In this project we see how to build a measuring wheel designed to be used over distances where rulers and tape measures are no longer practical. Even if it uses a rotary encoder with only 20 steps per revolution it can still provide good quality results by measuring, for example, the size of a room….
Peter Balch, reading an IEEE report on speech recognition from the late 1970s, wondered if, with a normal Arduino Nano, it was possible to obtain the results of a computer of the time. Comparing the two tools a Nano has 2 KB of RAM, 32 KB of program ROM and runs at about 10 MIPS…
There are probably more than a hundred Arduino-based printing machines on the internet with instructions available for making them. What makes this project unique is the built-in camera and screen. Other plotters must be connected to a computer, this works completely independently. The 20fps video shown on the screen makes it easy to capture images…
