Code for this frequency measurement using arduino is quite simple and easily understandable. Here we are explaining the pulseIn function which is mainly responsible measuring the frequency. The Uno has a special function pulseIn, which enables us to determine the positive state duration or negative … See more 1. 555 timer IC and 74LS14 Schmitt trigger gate or NOT gate. 2. 1K Ω resistor(2 pieces), 100Ω resistor 3. 100nF capacitor (2 pieces), 1000µF capacitor
