I need you to write a reliable arduino sketch that detects when pwm signal goes to A0 pin and turns on a relay until the pwm signal stops.

Hello. Do you need to detect the PWM signal only (i.e., any other signal mst be ignored). If yes - It's possible to use digital pins for more reliable detection? May I know the amlitude (voltage) and frequency of your input signal? With best regards Maxim

Hello, I'm interested in your project and I have some questions. Which is the frequency of the PWM signal? Do you need to detect just the presence of the PWM signal or do you need to detect other characteristics like duty cycle, freq, etc? When there is no PWM going on, Which is the value of the signal high or low? I look forward to your reply. Thank you.

Hello, I have an Arduino, and a signal generator, so I can generate and test the code with any required signal and of course proof it is working. I work fast and report periodically. Of course consultation on integration of the code in your device/project will be provided, until the code is accepted by you for a working one. If you have any questions or anything at all, I am available for a chat. Best Regards, Mihail Vrachanski

Hello there, Since you are willing to use an analog input (A0 in your case) for sensing existence of PWM signal, there will be no use for an external interrupt while they are only supported on pin 2 and 3 as interrupt 0 and 1. Either we can smooth the digital PWM using resistor and capacitor and read as analog or just use PulseIn command to read the value. Note that: PulseIn will keep CPU cycle occupied until the signal goes LOW! If you don't use any other heavy process with the CPU, it is just fine. Thank you and good luck with your project. Sener

Hello Sir, I Mouaz Imran from Appxone. I understand your requirement. I also can send you simulation of this project on proteus. But first i want to ask some questions 1) What frequency you need for your pwm signal? 2) Which driving circuit you are using for relay and can you tell me your relay specification? 3) Is there any problem if i use Timers instead of analog pin? Thanks Mouaz Imran
