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 ...

A ping is sent from the HC-SR04 ultrasonic distance sensor and Arduino measures the time it takes for the ping to return back after hitting an object placed at a known distance from the sensor. Speed ...

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 ...

An Arduino Nano microcontroller provides a simple and cost-effective platform for battery measurements and testing. When paired with TestLab software on a PC, setup and operation become ...

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 ...
