I will be testing to see if I can do this with an Arduino UNO and an external power supply for the fan, see attached wiring diagram "Schematic". Note that I've switched the LED strips, and already validated the electronics around it Software PWM will not be able to generate as high a PWM frequency as hardware PWM (at least not on the regular AVR-based Arduino boards) and to achieve a reasonably high frequency on multiple pins your code is going to need to spend most of the clock cycles just dealing with the software PWM. I pin digitali 3,5,6,9,10,e 11 riportano scritto PWM (e sul circuito stampato reale dell'UNO Rev. 13: 67289: May 6, 2021 Which version of servo. 6. I've been reading a lot of posts out there, but there seems to be a couple of libraries out there to choose from (Arduino Servo library included in the IDE, and a Software Servo library, etc. Hi guys so Ive read that the standard pwm frequency on(UNO) pin 5 and 6 are close to 980hz which is 0. I see that the board shows a special symbol for certain I/O pins indicating that they can drive PWM output, so I'm concerned that the neopixels might need PWN and t herefore b I am trying to generate two 100KHz square waves to drive a full-bridge inverter using an Arduino Uno, with the following code: TCCR1A = bit(COM1A0) // toggle OC1A on Compare Match | bit (COM1B0); // toggle OC1A on Compare Match TCCR1B = bit(WGM12) | bit(CS11); // CTC, /8 prescaling OCR1A = 9; // (9 + 1) * 8 CPU cycles -> 16 MHz / 80 = 100 Pins PWM. If you are not using the pin for PWM, it is available for you to use as required. It's misleading that Arduino uses "analogWrite" as the function name (a better name would have been "pwmWrite"). Can you suggest me how should I connect this. In the setup function, the statement pinMode(PWM_out_pin, OUTPUT); In analogWrite() - Arduino Reference it says, " The frequency of the PWM signal on most pins is approximately 490 Hz. In the following code I use Pin 9 as a PWM output, which should be toggled by compare register A interrupt. That symbol tells us that these pins have PWM support. I've been pouring over atmel doc for days trying to untangle all the various cryptic bit and register names and thought I had it sussed. Arduino Uno has 8-bit PWM channels. On the Uno and similar boards, pins 5 and 6 have a frequency of approximately 980 Hz. Google "Arduino Pinout", and look for one that shows things like OC0A next to the PWM pins - OC stands for Output Compare (the mode Using PWM, a pin is selected and its voltage is switched between 5v & 0v extremely fast, with the pin staying on each voltage for a variable amount of time. Most pages Ive googled say the best frequency to run dc motors are around 16khz .
