This current will then fall down 150 – 200 mA as the motor gains speed to around. In this case current flows to the base of both transistors due to which both transistor turns on (acts like an closed switch). Share it with us!   analogWrite(6,y); Vibration motors require more power than an Arduino pin can provide, so a transistor is used to switch the motor current on and off. NOTE: Please note that relay mounted on this board is 5v, not 12v relay. The circuit diagram to interface single DC motor with Arduino Uno using L298N for Arduino DC motor direction control. Now the voltage between the wiper terminal of potentiometer and Gnd determines the PWM voltage at pin no 6 and as wiper terminal is rotated, voltage at analog pin A0 changes causing change in speed of motor. With the transistors that are used by the library, when flat side of the transistor facing you the left leg is the emitter, the middle leg is the base Speed Control Pins :ENA and ENB are used to turn the motors ON, OFF and control its speed. but the question is that cw and ccw movements are not same.
