To be more motivated during exercise, Nikolas has decided to make a Smart pull-up bar using an Arduino Nano which, when you start exercising, will start playing music and will give it a Tic Tac at each set period of time as a prize. A laser diode and photoresistor located at opposite ends of the…
Who has never left their phone in one place and realized too late that they have lost it? In this project we will look for a solution to the problem; whenever you are too far away from your phone, “Don’t Lose Me” will blink and whistle, as well as your phone will play an annoying…
A very cool project you can do with an Arduino is to use it as a custom controller for your favorite games. Whether you’re adapting a Nerf gun or playing an FPS game, using an Arduino makes it quick and easy to build your own custom controller. In this tutorial, we will see how…
Have you ever wanted to know the temperature of your home anywhere in the world? Do you want to add a function to your weather station or monitor the air in your workshop? Let’s take a look at this project! The system consists of a sensor module that measures various environmental variables, which sends its…
Do you know what a “Wordclock” is? A Wordclock is a clock that displays the time by lighting up certain letters, contained in a matrix, in order to write the words corresponding to the current time. In this project we will see an alternative Wordclock using 3D printed letters, which will move through a magnetic…
This ECG (electrocardiogram) unit has an integrated 2.8 “display. The latter can show individual heartbeats in two different formats and a Poincaré texture. It is battery powered and can be worn around the neck on a lanyard. The device is based on an Arduino Nano, which receives data from ECG sensors and displays them on…
Have you ever wished to have an extra pair of hands in the lab to handle the camera while you are focused on your project? In this article we will build an automated assistant camera, which can automatically move to specific positions chosen previously or, alternatively, pan continuously from the top of the workbench. The…
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…
If you are a music composer, or just use your PC to record your musical instrument, you know how useful a MIDI controller can be in order to change certain parameters on the fly. Let’s see how to build one at home with potentiometers, buttons and an Arduino. To use an Arduino as a MIDI…
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…
If you are a Maker you have probably had to measure the doses of epoxy and maybe get the wrong ratio. If so, with this project we will see how to build an epoxy resin vending machine inspired by beverage dispensers. The project is based on an Arduino Nano that controls two 12V solenoid valves…
Most bench drills have a ruler to read the drilling depth. The greater the accuracy at which the desired position can be read, the greater the success of the job. In this project we see an alternative proposal: a display in which we see the drilling depth thanks to a gyroscopic sensor and an 8-digit…
