This tutorial will guide you through the process of building a tachometer around an Arduino. Tachometers are used to measure rotation rate in Revolutions Per Minute (RPM). You don’t need much… ...

Suppose we set the following parameters: Angular rotation (easier to calculate than linear motion) 90 DEG angle is our path Time to travel: l minute (from 0 to 90 DEG) Following this calculation 90 ...
