In this project we will see how to build a heart rate detection system, we use a pulse sensor and an OLED display, all controlled by an Arduino Nano. The sensor detects the person heartbeat and converts it into electrical signals and pulses. The signals are amplified using a signal conditioning circuit and processed by…
In this project we will see the difference between a coin acceptor and a servo using an Arduino nano to drive them. More info
The aim of the project is to measure the energy consumption of the hoverboard during different driving situations. For this reason, Niklas Roy decided to develop a power meter similar to the car’s on-board computer. Roy’s handheld device is controlled by an Arduino Nano and utilizes a Hall effect current sensor. The measurements are shown as…
Thanks to the acoustic waves generated by transducers you can make small objects levitate in mid-air. Now you can create this technology (initially used in research labs), even in your home. The main components are an Arduino Nano, an L298N module and 40kHz transducers mounted on a 3D printed support whose model is available. More…
Having too many people in one room with poor ventilation can lead to unsafe conditions and an increased probability of sharing airborne viruses. With this instrument you can track the air quality and visualize historic trends. With this monitor, you can immediately see the local air quality on the 8 pixel LED strip and you…
3D-printed clock with 24 analog faces that combine to form a single digital display. The overall device is controlled by a single Arduino Nano, which keeps track of the time using a RTC module. This unit coordinates 24 other Nanos on custom carrier boards, which in turn drive their own little clock face via a…
This video is a tutorial on how to control Common Cathode 8×8 LED matrix without the use of any driver chips like MAX7219 and corresponding libraries but just an Arduino Nano. More info
Arduino Smart Control allows you to communicate with your Arduino Nano through the Serial. It is possible to switch from one to 4 LEDs (monostable and bistable mode). The bistable mode has a time set to 1 second by default. In addition to switching the LEDs, you can monitor various sensors such as temperature, humidity,…
By having an automatic faucet, you do not have to touch the surface of the faucet after you wash your hands; you can wash your hands safely and prevent coronavirus disease. The main components will be Arduino Nano, Ultrasonic sensor and relays module More info
[Lewis] of [DIY Machines] was always on the lookout for that perfect something to hang above the couch. After spending a lot of time fruitlessly searching, he designed and built this awesome shelving unit with recessed lighting that doubles as a huge 7-segment clock. The clock part works as you probably expect — an Elegoo…
This project is an astronomy educational tool teaching about stars’ constellations, where the user can pick and choose any constellation they would like out of 15 different ones. The dome is manually rotatable so the user can imitate the relative movement of the stars. To make this project we will use an Arduino Nano and…
Intellisaurus is intended for many skill levels. There is no soldering or programming required to build and play with it. With a little more in-depth involvement you can connect the AI hardware and enable Google Assistant or Alexa. Impress your friends with a smart speaker that also walks. If you consider yourself a true maker…
