For the “common” PWM, if we write a value from 0 to 255 on a PWM pin, the Arduino library will drive the assigned pin to output a PWM signal whose on time is in proportion to the written value.

Pin 9 generates a PWM signal using a time-honored technique. Suppose you want to generate 20/255 (about 8% duty cycle). ... Just using the Arduino as a function generator will have its uses.

Unfortunately, the AD9833 doesn’t have a way to control amplitude, something which is pretty important in a function generator. So [Faransky] uses a X9C104P 100KOhm 8-bit digital potentiometer ...

Provided is a downloadable “clean” sketch (Ardu_Sinewave.ino) for the sine wave generator, which is, in fact, an adapation of the wonderful work by Ken Boak and Trystan Lea.To test this, just attach a ...

Arduino can deliver high-speed PWM For a long time I have admired the pulse-with modulators designed into Atmel (now Microchip) AVR microcontrollers . The company was early into adding phase-locked ...

PWM pins work the same way across all Arduino boards, so you don't need to go out of your way to buy a Mega if you already have a board supporting PWM. On the Uno, Nano, and Mini, the PWM pins are ...

The LT3761 is a 60 V dc/dc controller designed by Linear Technology to operate as a constant-current source and constant-voltage regulator.
