So feeding opposite voltage to reverse it probably spiked the current. Motor 1 Reverse4 ............... As a quick cheat I have included a list of PWM pins for the main two types of Arduino's I use:AT MEGA – PWM: 2 to 13 and 44 to 46. I connected two Arduino Pins with PWM functionality (Eg 45 and 46 on the Arduino Mega) to EnA and EnB. http://vinaprosoft.com/motor-driver/l298-dual-h-bridge-driver.php
I tried removing it and the entire chip would not function at all.2) I took out the jumpers from PWM pins EnA and EnB. I have a board that implements most of this parts features I did for a work project, but I never thought about selling any copies because they would be too expensive to high? Will order again. (Posted on 8/9/17) Excellent product Review by Bud Back to top General Worked well.
I do not know what i am doing wrong. So all together it’s $63 dollars to buy it from CanaKit and have it shipped within the same country. In my setup I gave it 3.3V. Will I be ok driving the motors with this setup?
Stopping To remove power from the motors, simply set ENA=LOW for Motor A and ENB=LOW for Motor B. Provide 8-bit PWM output with the analogWrite() function.Step 4: Arduino Sketch Example:This code example I wrote to allow a serial monitor program such as Putty to control the L298N Dual H-Bridge Refer to the details below.

The longer the pulses the faster the wheel will turn, the shorter the pulses, the slower the water wheel will turn. http://vinaprosoft.com/motor-driver/l298-dual-full-bridge-driver.php Then because I’m buying from Canada I have to pay 15% sales tax which brings it to almost $45.

I connected a stepper motor to A and B output, left the 5 volt and both enables jumper in place, connected the IN1-4 to arduino 8-11, feed the arduino with the L298n Module Datasheet The emitters of the lower transistors of each bridge are connected together and the corresponding external terminal can be used for the con-nection of an external sensing resistor. Do not enable the onboard 5V regulator if you plan to supply more than 16V to your motors.
