And he really bought me lunch because I located it for him smile So let me rephrase that: Thanks for lunch! The motor driver vs heatsink stack-up on the other hand is what I would expect from this price point: abysmal. This is where the L298N motor controller comes in. This L298N Motor Driver Module is a high power motor driver module for driving DC and Stepper Motors. An H-bridge schematic looks like this: Here, the motor rotates in the direction dictated by the switches. Reply The L298 is a dual bidirectional motor driver, and allows for easy and independent control of two motors up to 2A each. It also has six pin male headers for connecting the two enable inputs and the four input pins (two for each motor). With this motor driver you can control DC motors, stepper motors, relays, and solenoids. And that's it, you've programmed your Arduino board! The chip is optimized to drive the inductive loads such as relays, solenoids and DC motors. For example try to combine parts of code to move both motors simultaneously.Try to use analogWrite(pin, PWM value) instead digitalWrite(pin, HIGH/LOW) to control the speed of motors!
