Have some questions
For a project I have to make a speedometer with a hall sensor.
Have you read a lot about this already and only have a few questions?
You can measure your rpm by measuring the time between 2 pulses and then calculating rpm or measure the amount of pulses in 1 sec.
Which of these is the most accurate?
Maybe somebody already has what I'm looking for?
It is a circuit with a hall (https://www.gotron.be/arduinor-compatible-magnetic-hall-holzer-sensor-2-st.html) and a lcd 16x2
Thanks in advance for the help
