Reading DC fan RPM with Arduino

Source: http://www.theorycircuit.com/reading-dc-fan-rpm-arduino/Reading DC Fan RPM (Revolutions per minute or Rotation per minute) is very easy than we think, yes because DC fan internally contains Hall Effect sensor, So we need to count the output pulse from the Hall Effect sensor that’s it. 3 Wi…By: theorycircuit Continue Reading » Instructables: exploring


Reading Temperature From PT100 Using Arduino

The PT100 is a resistance Temperature Detector(RTD) which changes its resistance depending on its temperature surrounding temperature, its used widely for industrial processes with slow dynamics and relatively wide temperature ranges. It’s used for slow dynamic processes because RTDs have a slow res…By: Roboro Continue Reading » Instructables: exploring


PCB Repair reading schematics 101: Electronic circuit reference abbreviations and symbols

In this instructable I will talk about how to read a schematic and how to identify electrical components on a PCB (Printed Circuit Board).Electrical components are identified two main ways. AbbreviationsSymbols.On a schematic you will also see a electrical components symbol next to it will have a id…By: robmawe91 Continue Reading » Instructables: exploring
