In exploring the use of analogWrite() and digitalWrite() on the Raspberry Pi Pico using Arduino, I have discovered some strange behaviors when switching between those modes on the same GPIO pin. This ...

I wanted to do something really simple. Having several LEDs controlled by PWM. Everything was working very weird with analogWrite so I tried several boards and reduced the setup to the minimal. It is ...

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 ...

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 ...

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 ...

I have been delving (groping blindfold, more accurately) into the Arduino compiler adaptation code to try to determine how it handles the switch-over between its pwm activities, its set-I/O-to-output ...

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 ...

Abstract: DDS (Direct Digital Synthesis) is a method to produce analog waves using digital techniques. Analog waves can be sine waves, square waves, triangular waves, or others. This research used ...
