The reason for the 0/255 check is simply that using Fast PWM you can not go to zero, when you are say using an LED under PWM, having it not go to zero is very noticeable, it’s effectively a runt ...

Getting down to Arduino basics, PWM output is possible in an Arduino (Uno) on its digital I/O pins 3, 5, 6, 9, 10, and 11. Here the “analogWrite” function can be used to set the PWM duty cycle. To ...

Wire an Arduino to a couple of pots, as described in pwm_explorer.ino. Upload pwm_explorer.ino to the Arduino. One pot controls the frequency, and the other controls the duty cycle. They flash the ...

The Atmega 328P chip in the Arduino Uno has three PWM timers (known as Timer 0, Timer 1, and Timer 2) controlling six PWM outputs. Each of the timers has a prescaler that generates the timer clock by ...

Circuit diagram of the low-cost PWM module with two outputs. Description of the proposed circuit. Figure 1 presents the circuit diagram of the low cost PWM module with two outputs. The circuit ...

Create a TurboPWM object (called pwm here, but name as you wish): TurboPWM pwm; Set input clock divider and Turbo Mode (which uses a 96MHz instead of a 48Mhz input clock): pwm.setClockDivider([1-255], ...

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 ...
