H Bridge Stepper Motor Arduino. The l298 is an integrated monolithic circuit in a 15 lead multi watt and power s020 package. You normally use it with a microcontroller such as an arduino to control motors.
Connect pin1 of the h bridge to the positive side of the 5v rail on your breadboard. 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. You could also use the arduino s dc power jack and power the motor from the vin pin.
This makes the l298n dual h bridge motor controller very versatile if your project is using a lot of arduino pins.
You can upload the following example code to your arduino using the arduino ide. As a quick cheat i have included a list of pwm pins for the main two types of arduino s i use. The 4 logic pins will then connect to the arduino 8 9 10 and 11 in this tutorial. Using l298n h bridge with stepper motors on arduino.
