Hello all seniors, i'm new on here so please If there is any mistake, please forgive. I want to know about arduino, can i get 3pmw vairiable signal by arduino. kindy help me.

 

Welcome to AAC. Could you please be a little more specific? If you are asking about having 3 simultaneous, different PWMs, it is certainly possible. You just need to use millis(). What exactly do you need these PWMs for, and what kind of input must control them?

 

Also what frequencies, and what type of precision do you need? And which arduino are you looking at? The Uno uses the Atmega 328p processor, here's one (of many) PWM examples:

Uno has 6 pwm pins.

For control input analog 0-10, or two pusbutton freuency increase or descrease

Uno has 6 pwm pins.

How can i ganerate, please give some essy tips. I'm beginers for arduino

 

Hello,

Uno has 6 pwm pins.

But all pins are capable of PWM with the resolution * frequency being equal to the clock speed. It's just that only 6 or so allow the "analog write" function at a higher frequency.
