When coding Arduino projects for other people (and myself) I find having ASCII art pinouts of the hardware very helpful. It allows me to very quickly see the pin assignments and pins used. Please feel ...

This project controls an Arduino connected via USB using RS232 communication through the network, using an node/express server. A single route in the API receives a query parameter that contains a ...

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 ...

Community collaboration is a great thing. Take the Arduino PWM library for shift registers. Some folks at the Arduino forum pitched in and helped [Elco] trim off a bunch of clock cycles by using the ...

The purpose of this project is to provide a 4-20 mA output from a PWM signal generated by a microcontroller. One of the more interesting applications of this circuit would be to replace or to realize ...

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 ...

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 ...

Abstract: This paper presents a simulation of a buck converter using pulse-width modulation (PWM) signal frequencies and duty cycles generated by an Arduino microcontroller for solar panel application ...
