Measuring current is both easy and very accurate using a current sensing module and an Arduino. PCBWay $5 for 10 pieces https://www.pcbway.com PCB Prototyping the easy way - see my video #129 for ...

Discover how you can build a professional digital multimeter using Arduino that measures up to 24V DC voltage, checks resistance, conducts diode testing, and performs continuity tests. This ...

In my previous post, I used blinking videos on my computer to entrain my brain waves. A key question, though, was whether my computer could play those blinking videos steadily. If the blinking isn’t ...

I decided to make a 'Pulse Oximeter' because, in this pandemic situation, we need this device a lot. It helps us to measure the BPM(Beats Per Minute) and the percentage of Spo2 of our Body. I used ...

This project is designed to measure heartbeat with an Arduino with heart beat sensor module. The Arduino then does a Fast Hartley Transform (FFH, alternative for Fourier) transform to generate the ...

Denis Hennessy recently encountered a problem we've all faced: he needed some AAs for a battery-eating gizmo, and he was overwhelmed by the choices available. Ignoring the shiny packaging and its ...

If you frequently use a 3D printer for your projects then you may experience issues calculating the material weight and length usage. If so, then you might be interested in this project using Arduino.

Abstract: This paper presents the performances of rainfall energy harvesting through the use of a piezoelectric transducer and an Arduino-based measuring system. Diverse studies agree on the ...

Eh, what? Blimey... This project, dubbed the ardEEG shield, aims to use an Arduino UNO R4 WiFi as a brain-computer interface! The result of several years of work on the development of a brain-computer ...

A bit of biology and nutrition before we roll into this: Ketosis is when your body runs on fat reserves instead of carbohydrates. This is the basis of diets such as Atkins, and despite the ...
