In this project we will see how a machine was built that takes out your tea bag when the previously set time expires. The Steampunk-style structure was built with 4mm plywood cut out using a laser engraver. As for the electronics, there is an Arduino Nano that controls a servo motor after the set time…
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…
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 article we will see how to build a fire and gas detection system that also provides protection. We use Arduino Nano as a microcontroller and two sensors: MQ-2 gas sensor and the flame sensor. We use a 16×2 LCD display to view live status. There are also PCB designed dual channel relays to…
Control any MIDI parameter value of your DAW through hand movements. The first controller was made using the knobs of a potentiometer, however the functionality of the knob is only to send values from 0-127 and this can be done by any means, so we thought of using the ultrasonic sensor. This design has been…
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…
With this project you will be able to build your own fighting robot at home. The shell is laser engraved but of course you can also print it in 3D. The robot will be controlled by an Arduino Uno powered by two 18650 batteries charged by a normal charging module on the back. The robot…
In this project we will see how to recreate the Snake game on a matrix of LEDs. After loading, the game will automatically start with the snake in the lower left corner. An apple will randomly spawn and you can start moving the snake with a joystick. We have an 8 x 12 matrix of…
This robot translates Twitter activity into Cocktails of different flavors. When you want a cocktail, the machine will search for the latest five messages around the world mentioning one of the available ingredients. These messages define the composition of the drink and not only will the result be unique, but the cocktail recipe will also…
Do you usually have trouble getting up? You set a dozen alarms in the morning, but still can’t wake up? In this project we will try to solve the problem in an alternative and quite creative way by building an alarm clock that will ask random questions. It will stop making noise only if the…
The following project consists of a small computer for children which, upon entering the correct name, displays the respective image and sound. The project is based on an Arduino Mega, which receives the signals from a keyboard and displays the writings on a 16×2 character display and the images on a 2.8 “LCD display. The…
