The ATMega328 microcontroller as mounted on the Arduino UNO board has a 10-bit AD converter. Let’s use its function analogRead to measure some voltages with. How can we improve the accuracy of the ...

In this project, we'll go over how to interface a 4x4 membrane keypad with an Arduino microcontroller. By the end of this tutorial, you'll be able to read the state of the keypad and determine which ...

In this video, the presenter is going to give you a quick overview of LTC2945 wide range I2C Power Monitor. He will also give you a quick demo how to measure current and voltage using Arduino and ...

d) To maximise measurement resolution, the voltage across the burden resistor at peak-current should be equal to one-half of the Arduino analog reference voltage.

There are various ways to interface a laser with Arduino depending on the application. A laser diode finds applications in CD/DVD reading and recording, optical-fibre communications, laser printing ...

So in this tutorial, we decided to interface the SD Card module with Arduino and we will let you know all the details. So without further ado let's get right into it. Micro SD Card Module Pinout The ...

Arduino_PLC_interface A quick and dirty interface that allows an Arduino to act as an industrial PLC input. ##Design Notes The first stage is a simple RC network to covert the Arduino 490 Hz PWM ...
