Maximum motor supply current: 2A per motor.ġ x L298N Motor Driver Module – Good Quality. ![]() Provide 8-bit PWM output with the analogWrite() function. The int“speedPin(letter)” pins need to be connected to a PWM pin on the Arduino if you want to enable speed control through PWM.Īs a quick cheat I have included a list of PWM pins for the main two types of Arduino’s I use: This makes the L298N Dual H-Bridge Motor Controller very versatile if your project is using a lot of Arduino pins. The “int dir(number)Pin(letter)”‘ pins can be connected to any available digital pin you have available, as long as you declare the correct pin in your sketch. ![]() Since there isn’t a library for the L298N Dual H-Bridge Motor Controller you just have to declare which pins the controller is hooked to. The Arduino code sketch is pretty straightforward. The PWM Pins are unnecessary if you do not want to control PWM features.Make sure you have all of your grounds tied together Arduino, Power source, and the Motor Controller.Out 1: Motor A lead out Out 2: Motor A lead out Out 3: Motor B lead out Out 4: Mo (Can actually be from 5v-35v, just marked as 12v) GND: Ground 5v: 5v input (unnecessary if your power source is 7v-35v, if the power source is 7v-35v then it can act as a 5v out) EnA: Enables PWM signal for Motor A (Please see the “Arduino Sketch Considerations” section) In1: Enable Motor A In2: Enable Motor A In3: Enable Motor B In4: Enable Motor B EnB: Enables PWM signal for Motor B (Please see the “Arduino Sketch Considerations” section) Motors will last much longer and be more reliable if controlled through PWM. The longer the pulses the faster the wheel will turn, the shorter the pulses, the slower the water wheel will turn. Take the water wheel analogy and think of the water hitting it in pulses but at a constant flow. Motors are rated at certain voltages and can be damaged if the voltage is applied to heavily or if it is dropped quickly to slow the motor down. The voltage would be the water flowing over the wheel at a constant rate, the more water flowing the higher the voltage. In motors try to imagine the brush as a water wheel and electrons as the flowing droplets of water. * Pulse Width Modulation is a means in controlling the duration of an electronic pulse. How it works:Īn H-Bridge is a circuit that can drive a current in either polarity and be controlled by *Pulse Width Modulation (PWM). H-bridges are typically used in controlling motors speed and direction but can be used for other projects such as driving the brightness of certain lighting projects such as high powered LED arrays. The L298 Stepper Controller makes it easy to drive either two DC motors or a bipolar stepper motor. ![]() The module is based on the L298 chip which is a high voltage, high current, dual full-bridge motor driver designed to accept standard TTL logic levels. This L298N Motor Driver Module is capable of driving inductive loads such as relays, solenoids, DC and stepping motors.
