Once the code is uploaded, you should see the motors turning one way and then the other. Constants #define nbL298N 2 //Parameters const int enaL298NPin = Result Controlling the stepper motor from your sketches is very simple, thanks to the per Arduino library. Finally, connect Arduino GND to point 5 on the module, and Arduino 5V to point 6 if sourcing 5V from the module. The forward or reverse direction of rotation depends on the direction of the motor connection. Step 1: Fritzing Diagram Fritzing Wiring Diagram: The attached Fritzing diagram shows the various connections from the batteries, via the two-pole switch, to the Arduino Uno. Next, connect L298N module pins IN1, IN2, IN3 and IN4to Arduino digital pins D8, D9, D10 and D11 respectively. Then, send a PWM signal to the Forward (Input1/4) or Reverse (Input2/3) pin to control the direction and speed of rotation. To use the L298N module, you have to activate the H-bridge by applying a 5V voltage on the EN pin. This allows to always activate the H-bridge and to save two outputs of the microcontroller L298P Motor Driver Shield - ProtoSupplies The L298P Motor Driver Shield is a multi-featured motor shield based around the L298P driver chip and is compatible with Uno and similar Arduino boards.
See FAQ:Where can I find “specific part” for information about looking for existing part files, and information needed to create new parts.On some models of this module, it is possible to add two jumpers to directly connect the enable pins (ENA and ENB) to 5V. Either as is, or as a base for something else. I would not try to use that downloaded part with out some serious cleanup first. To figure out where things are supposed to be, and what should be connected together. To do this properly, a datasheet for the part is really needed. What I see does not have labels except on breadboard, and the part validation tool I use has many complaints. Jumper wires (or cable) would run from the board to a header on the pcb instead. Really, this board does not normally need a pcb view. So if you need to drive two motors, you have to instantiate two L298N objects (one for each motor).
NOTICE As you know, any L298N module has the ability to drive two motors at once, but you may not know that one instance of the library is intended to pilot only one motor. Spacing and position of the pins on the pcb view also look off. L298N Library An easy to use L298N library to control DC Motors with Arduino.
I do not see any of that in the part definition though. Like multiple gnd, or +5V connecting to other +5. Wires are not connecting where they are dragged to except in breadboard view.įewer pins in schematic “CAN” be normal, in cases where multiple physical pins are connected together inside the part. My initial testing of a fresh download of that part says it is broken.
