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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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: The purpose of the projects is the development of measuring devices. These devices measure capacitance, distance and temperature. The main platform for instrumentation modeling was the ...

Electromagnetic interference problems can be a real headache to debug. If you need to prove what causes your WiFi to slow down or your digital TV signal to drop, then the ability to measure ...

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 ...

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 ...
