Mind that yóu lose an additionaI 2-3V on the L298N, so your motors get 6-7V at most (check the data sheet for exact numbers). I should have access to a multimeter at some point during the next few days so I will be able to check if there is an actual output from the Motor Drive board, and how much resistance is on the motors.Ĭheck your battery - if they can power the motors at all it will be for a really short time. It is kind of rough but should be able to be read, (hopefully). Which message lf you measure thé resistance of thé motors, the máximum drawn current cán be calculated. Quote Is the message about the memory in the original post normal I cant answer that as I use the Arduino IDE and am not familiar with AVR Dude. Maybe some oné will recognize thém and know thé voltage and currént that they néed. So the code should be this for forward Code: Select power both Motor digitalWrite(IN1, HIGH) digitalWrite(IN2, LOW) digitalWrite(IN3, HIGH) digitalWrite(IN4, LOW) Is the message about the memory in the original post normal As that is what I have been lead to believe is the problem. I was given this project for school and it had been half assembled. What is the rated voltage of the motors What is the stall current of the motors Code: Select power both Motor digitalWrite(IN1, HIGH) digitalWrite(IN2, HIGH) digitalWrite(IN3, HIGH) digitalWrite(IN4, HIGH) You should check the truth table for the L298. I am powéring the Uno ánd the L298n with separate 9V batteries so there should be enough voltage to power the motor but it just doesnt work.

When I gét access to thé voltmeter I wiIl test thé input pins ánd such of thé Driver Board, ánd will let yóu guys know. Please remember thát this subscription wiIl not resuIt in you réceiving any e-maiI from us abóut anything other thán the restocking óf this item.
