This project uses the Arduino Uno PWM output to realize a fully isolated analog output with a range of 0..5 V or more. The use of an averaged PWM signal is not comparable with a real DAC, but it has ...

The company was early into adding phase-locked loop clock multipliers to give the PWM machinery something faster than the processor clock to work with. Arduino offers a simple framework to programme ...

Using DSO138 Smart Oscilloscope for Testing Arduino Signals The DSO138 smart oscilloscope is a compact and affordable tool for signal visualization. It can be used to test and debug signals generated ...

Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...

Most projects are built on abstractions. After all, few of us can create our own wire, our own transistors, or our own integrated circuits. A few months ago, [Julian Ilett] found a problem using the ...

I wrote this when I could not find Arduino code online that could accurately and reliably read 25kHz pwm signals. For reliable PWM you must handle the following edge cases: 100% or 0% PWM signal with ...

When multiple PWM converters are connected in series (or in parallel) in a power electronics circuit, it is appropriate to run all converters at the same frequency but with certain phase shift among ...

Animate multiple 24 VDC LED garlands with flashing and variable brightness (13 different parameters) with one Arduino Nano multi-tasking with FreeRTOS. After my previous project with one Arduino ...

A PWM signal requires just a single digital output on an IC and so it is hardly surprising that these days the digital I/O pins of microcontrollers often come with extensive PWM capabilities. However, ...

Want to spice up your Family Board Games night? You'll love the "Arduino Digital Dice" project! This project is also available at Max Imagination's Workshop. This innovative circuit combines the ...
