But, the Arduino developers (Wiring maybe, this is old stuff) could easily have solved this in a much more efficient way by simply using the inverted Fast PWM mode instead of non-inverted.

Arduino PWM. As you may know, two PWM outputs of Arduino Uno are linked to the timers. For the “common” PWM, if we write a value from 0 to 255 on a PWM pin, the Arduino library will drive the assigned ...

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 th… ...

Arduino Gemma from Adafruit is also based on the ATtiny85, and PB0 and PB1 appear to be accessible. This board has a USB connector for programming and a voltage regulator. This board, which I am ...

This is a random oscillogram from D5 of Arduino Uno. During experiments, I powered my Arduino setup with a Li-ion 9V/600mAh USB battery. Quick note: Arduino UNO has three timers – D5-D6 on Timer 0 ...

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 ...

Prestissimo Uno+ Arduino dev board with extra I2C UART SPI ADC IO and PWM channels. 2:24 pm November 5, 2018 By Julian Horsey ...

Arduino enthusiasts or those looking to build a binary clock may be interested in a new shield created by developer Marcin Saj. ... The buzzer is connected to the Arduino pwm pin “11 ...
