measuring encoder pulse amplitude with Arduino IDE

HI -

I, do not have a oscilloscope, instead want to monitor the amplitude of a pulse encoder, any links available to do so on Arduino IDE.

Thanks

What is the pulse frequency and how long is an individual pulse?

Read about the analogRead() function.

What the heck is a "pulse encoder"?

Hi Robin2 -

It is 100kHz, encoder output is square pulses - digital, I'm not sure if we can use analogRead may be PWM digitalRead could be used, I'm not sure.

Why do you need to measure the amplitude of digital pulses - they are either HIGH or LOW.

You need to go back to square 1 and tell us WHAT you are trying to achieve rather than HOW you think it should be done.

Robin2- when long cables are used - say 10mts+, especially where pulse amplitude at the origin is 5V or at TTL, they get attenuated - and may be nuisance trigger - could be in the levels of 2V that some times is read as low or gives false trigger

Why would you have encoder pulses traveling through 10 metres of cable? 1m would be very long.
