It’s something [mircemk] demonstrates, with an Arduino-powered magnetic field strength meter that uses a UGN 3503U Hall effect device. The circuit is extremely simple, comprising the sensor, an ...

Learn how to build a DIY current and voltage meter using Arduino Nano. This project demonstrates step-by-step instructions to measure current, voltage, and wattage with precision. Using simple ...

Here’s a turbidity sensor driver circuit based on LM393 for the intended task. Tweak it! On the Other Side. While I was experimenting with my old TSD-10 turbidity sensor lifted from a defunct washing ...

DIY Arduino Nano multimeter with LiPo battery, charger and more. 10:59 am February 13, 2019 By Julian Horsey.

With hopes of “making an engineer’s life easier and safer,” Mauer solved this problem using an Arduino Pro Micro and a BLE module to show data from a Bluetooth-enabled multimeter.

It runs on an Arduino MEGA 2560 PRO (or similar microcontroller) and supports a wide array of additional hardware including pressure transducer, water level sensor, flow meter, OLED display, and more.

Arduino has announced the availability of a design starter kit for the Genuino Uno embedded computing module. And if you want to design a LOVE-O-METER to measure how hot-blooded you are or a LIGHT ...

That’s right, these parking sensors are powered by an Arduino board, and the only extra components that were used in the project are a HC SR04 ultrasonic sensor, an active buzzer, and jumper wires.
