Note that the 5V regulated power on pin 5 above is an output when the 5V_EN jumper is in place. Hardware Details Screw terminal pin assignments As you can see the diagram below, Red, Green, Yellow, and Blue are connected into the l298n board pin. Place the jumper included with the L298n Module over the pin. Connect the A+,A-, B+ and B- wires from the stepper motor to the module connection OUT 1, OUT 2, OUT3, and OUT4 or A1, A2, B3, and B4. The stepper motor has 200 steps per revolution and can operate at 60RPM.

This characteristic makes it very suitable for digital interfaces integrates with a microcontroller. Since the stepper motor does move in discreet movement, we can say that a stepper motor is actually a digital motor. In the example below you may notice that there are 4 distinct steps for the rotor to make a complete 360 degree rotation. The stepper motor moves is distinct steps during its rotation.

It can also be interfaced with simple manual switches, TTL Logic gates and relays. It is excellent for robotics applications and well fit to a microcontroller. This module has ease to connect and drive a dc motor or stepper motor allows you to easily and intently control two motor up to 2A each in both direction or one stepper motor. Additional supply input is provided so that the logic works at lower voltage. The emitters of the lower transistors of each bridge are connected together and the corresponding external terminal can be use for the connection of external sensing resistor. Two enabled inputs are provided to enable or disable the device independently of the input signals.

It is a high voltage and high current full dual bridge driver designed to accept standard TTL logic level and drive inductive loads such as relays, solenoids and DC stepper motor. The l298 is an integrated monolithic circuit in a 15 lead multi-watt and power S020 package. , And then, while rotating forward and reverse for 2 seconds, stop twice for 1 second to make the wheels turn left and right.The L298 Dubai H Bridge is base on l298 Chip manufacture by ST Semiconductor. The following execution results make the two motors rotate forward for 2 seconds and stop for 1 second, then reverse for 2 seconds and stop for 1 second. When the motor stops rotating, the LED light will go out. When the motor rotates, the LED light on the Pi Pico development board will be on. Led = machine.Pin(25, ) #Set the LED on the development board (Pin25) Please refer to the following wiring diagram. The positive and negative wires of the two motors are connected to the left and right sides of the L298N module. The 5V power supplied by the breadboard is directly connected to the positive (+5V) and GND poles of the L298N module. The following table shows the action of the motor when the two input potentials of IN1 and IN2 (or IN3 and IN4) are high or low. IN4 inputs the PWM signal to drive the speed and direction of motor 2. After ENA and ENB are enabled (Enable), PWM signals can be input from IN1 and IN2 to drive the speed and direction of motor 1 from IN3 and IN2 respectively. The L298N module is a 2-way H-bridge driver, which can drive two motors at the same time. It contains two H-bridge high-voltage and high-current full-bridge drivers, which can be used to drive inductive loads such as DC motors, stepping motors, and relay coils Two Enable enable control terminals, under the condition of not being affected by the input signal, allow or prohibit only one logic power input terminal, so that the internal logic circuit part works at low voltage using the L298N chip to drive the motor, the chip can drive one A two-phase stepper motor or a four-phase stepper motor can also drive two DC motors L298N is a high-voltage, high-current motor driver chip produced by ST.
