I am very new to arduino so I apologise if my question seems trivial, but I have been unable to find an answer online. I am attempting to have the arduino generate a pulse. I understand that the arduino can output PWM, and that one can adjust the duty cycle of that outputted wave, however all that I can get it to generate is a constant square wave. I would like to generate a pulsing signal, which outputs a certain number of cycles over a given frequency. Is it possible to program the arduino to do this?
If the answer to the above question is "no, does anyone know of any external components that could convert a constant pwm to pulse over a given frequency? I appreciate any help that I get!
