In this project we will see how to make a simple bike dashboard that allows you to view speed, turn on rear and front lights and enable turn signals. The system is based on an Arduino Mega which controls two 1.3 “OLED displays to view data, several segments of WS2812 led strips used as lights…
Although it is human nature to touch one’s face for a variety of reasons, such behavior can facilitate the transmission of viruses and other diseases. If sheer willpower isn’t enough to avoid it, the head-mounted DesignMaker blueprint can be helpful. The device will give you a slap on the forehead when your hands and fingers…
With hydroponic cultivation we mean a different method of plant growth, in fact instead of the earth there is water with dissolved mineral salts that flows between the roots. In this project we will see how a hydroponic greenhouse controlled by an ESP8266 was built. The system consists of pumps and temperature sensors controlled by…
Dit-dit-dah-dah! Learn Morse Code with this easy Arduino Uno project. This easy Arduino project is a Morse Code station. Morse Code is a communication method that encodes characters as a series of dots and dashes. This circuit uses a piezo buzzer to make the dots and dashes audible. Using the button, you tap in the…
With this device you will be able to read the measurements made by a DIY multimeter directly on your glasses. No cables will be present as the multimeter will send the read data through the Bluetooth connection. For reasons of compactness a PCB has been designed but it is possible to do it directly using…
There are several ways to solder PCBs with SMD components. We have seen the oven, but there are also plates in which to place our board on top and wait for the solder paste to melt in order to solder the components on the PCB. In this project we will see how to build one…
This project allows you to create a low cost GPS data logger for RC aircraft. A Data Logger allows you to record data from sensors and save them in a micro SD memory. In this case, data from a GPS module will be recorded. During the flight, an Arduino Nano will receive data from a…
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…
After losing the chicken due to wildlife intruders, Elbie decides to create a Smart chicken coop with several functions: Opening and closing the door at sunrise and sunset according to local geographic coordinates; Intrusion detectors with flashing LEDs in two positions; LEDs visible from the outside to show the status of the door; Two buttons…
This project allows data from ECG electrodes to be read and processed in order to predict atrial fibrillation. To do this, the system will use a Machine Learning system (TinyML) which will compare the acquired data with other pre-set ones. The system acquires the signal of the ECG electrodes through an AD8232 module, which analog…
Due to the pandemic, many people have been forced to stay indoors much more often, which means missing out on the usual social events, including sports and tournaments. Even playing a simple game of chess hasn’t been feasible anymore, until now. Lewis of DIY Machines designed and built a smart chess board that allows you…
Bands on through-hole resistors conveniently indicate their value at a glance. On the other hand, you have to actually know the code to interpret this meaning. Alternatively, you could use the Ohmmeter 2.0. The Ohmmeter 2.0, based on Arduino Mega, has three modes. First, it enables you to enter resistor value with a keypad and…
