This is a series of simple projects aimed at getting started with Arduino. This will cover most of the important peripherals of the Arduino starting from simple using PWM and communication
interfaces etc which is used for controlling the motor

In the first set of projects the following are included. They are basically about the various motor control using PWM on the arduino.

1:L293 dc motor control
2:stepper motor control
3:servo motor control

In this we are going to see the experiment 

L293 dc motor control : 

connect a potentiometer as analog input to the pin A0 and a dc motor to the pin 9,10 . the dc motor cannot be connected directly to the arduino so using a l293 ic connect the motor to the arduino as per the circuit diagram.

when the potentiometer is varied the speed of motor increases and viceversa
