Many electronic devices make use of motor for its usage so in order to do it perfectly we need a circuit which could control the motor speed precisely.Here is a circuit which is capable of controlling a 12V DC motor.This circuit uses a IC LM2941CT which is a low drop out 1A voltage regulator.This regulator IC posses many cool features like power supply reverse protection, thermal protection, short circuit protection etc.The maximum output current IC can be around 1A.Now lets see the working of this circuit and how it was used to control the motor speed.

This is a very simple circuit which was used to detect the Electromagnetic field which was around us.The principle behind this circuit was mutual induction whenever a EMF was near a inductor mutual inductance takes place and due to this mutual induction it results in a voltage in the inductor.Using this induced voltage the EMF field was detected.Lets see the working of this simple circuit.
