Arduino-Resistance-Meter 1)Introduction: 1.1)Resistors are important electronic components that are used to oppose the flow of current. And hence, Resistance is the property of a material which ...

Components Required: Arduino Uno/Nano HC-SR04 Ultrasonic Sensor 16x2 LCD with I2C Module Buzzer Jumper Wires Wiring Diagram: How It Works: The HC-SR04 ultrasonic sensor measures distance by sending an ...

Circuit and working The circuit diagram of the digital frequency meter is shown in Fig. 3. It consists of Arduino Uno board, optocoupler MCT2E (IC1), 16×2 LCD and a few other components. The ...

No multimeter handy (for shame)? Well, as it turns out you can actually measure capacitance using your Arduino Uno, with no external components, and only ~20 lines of code.

This project demonstrates an Arduino-powered wireless frequency meter that can measure the frequency of sinusoidal AC transmissions ranging from 50Hz to 3kHz. Figures 1 and 2 show prototype ...

The build relies on that old stalwart, the Arduino Uno, to run the show. It’s hooked up to a DS3231 real-time clock module so it can keep accurate time for long periods, as is befitting a clock.

Programming Arduino Nano for Solar Irradiance Measurement Here we have programmed Arduino nano to initialize the BH1750 object using the default high-resolution continuous mode and then make a light ...

The parts arrived for the RPM meter that uses an Arduino and reciprocal counting to get a three-times-a-second update rate with 1rpm resolution. Arduinos ...
