The L298 is an integrated monolithic circuit in a 15- lead Multiwatt and PowerSO20 packages. It is a high voltage, high current dual full-bridge driver designed to accept standard TTL logic levels and drive inductive loads such as relays, solenoids, DC and stepping motors. Two enable inputs are provided to enable or disable the device independently of the input signals. The emitters of the lower transistors of each bridge are connected together and the corresponding external terminal can be used for the connection of an external sensing resistor. An additional supply input is provided so that the logic works at a lower voltage.
**give the drive voltage to power the motor's voltage
Can test IN1, IN2, ENA by using electrometer. connect one end to the legs of L298 and the other side to the 8 pins.
ENA usually at the back
IN1 and IN2 are at the left bottom side.
Connect VCC to positive to a transformer
Connect GND with arduino and transformer
IN1 and IN2 to arduino
ENA to ~PWM
