How to calculate frequency and duty cycle using Arduino?
· From total time the arduino calculates frequency as Frequency = 1 / time · And from Ton and Toff it calculates duty as Duty = Ton / (Ton + Toff)

How is Arduino used in the measurement field?
It can be used in measurement field also to measure electrical quantities (like voltage, current, power etc) or physical quantities (like temperature, moisture, light intensity, humidity etc) or electronic component values etc. The given article demonstrates how to measure frequency and duty cycle of pulses using arduino.
How can Arduino be used to measure pulse width?
In DC motor speed control and servo motor angle control it is required to measure width of pulse. Also the pulse width is measured to check the symmetry of pulse in some of the application like digital signal receiver, repeaters etc. So let us see how we can use arduino to measure frequency and duty cycle of pulses.
What are digital input and output pins for Arduino?
Though this is written for the Arduino microcontroller module, the principles apply to any microcontroller. Digital input and output are the most fundamental physical connections for any microcontroller. The pins to which you connect the circuits shown here are called General Purpose Input-Output, or GPIO, pins.
What are the features of an Arduino oscilloscope?
The oscilloscope features a 6-channel selectable input (A0-A5 pins on Arduino), separate trigger input with rising or falling edge trigger setting, continuous or single sweep mode, adjustable time base (100us-200s/div), and adjusatable sensitivity and offset per channel.
What is the amplitude of an Arduino audio signal?
The signal is relatively weak, with an amplitude of only 200mV, you may find that signals from other sources (ipods, guitars, record players…) also produce audio signals with small amplitudes. These signals need to be amplified to get them up to the amplitude we want (2.5V).
