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 ...

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 ...

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 ...

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 ...

Where pin is the number of the PWM capable pin you want to write to, and value is the duty cycle between 0 (always off) and 255 (always on). Explain why 0 volts corresponds to 0 and 5 V corresponds to ...

In adding an alternative cutter drive motor (‘spindle’) to an existing cnc machine, an electrically isolated pwm to analogue converter is needed. The machine uses a ‘grbl’ controller, which has an ...

I have been discussing control algorithms for a power supply and idly looking for some easy hardware on which to try the technique – hardware small enough to build into a prototype. See also: An AVR ...

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 ...

A step-up or a boost converter circuit converts a low voltage into a higher value output voltage. The circuit consists of an inductor, a capacitor, a diode and a switch (MOSFET) that’s turned on and ...
