Problem with my L298n Motor Driver

erik3dprints · September 23, 2023, 12:17pm

Im using a L298n Motor Driver to run two 12V DC Motors. It always worked perfectly fine. My motor shield gets powered by a 12V Power supply. I measured it and the 12V get there fine. Im running my DC engines with a 100% duty cycle of 255. I never had any problems running my engines. They always runned on 12V when i gave them the signal to run. Now since yesterday they just dont get more than 6 or 8 Volts max to run. My shield still gets the 12V input i measured that again. When i give my engines the signal to run the Arduino just send 1.5V on the pin to the motor shield. Honestly i havent measured that before the problem and idk if thats normal.

Maybe someone of you has an idea what could be wrong. I changed nothing on my code, nothing on my wiring it just stopped working how it should.

Hi,
Can you please post your code?
Can you please post some images of your project?

Please post a link to specs/data of the motors?

Thanks.. Tom..

1.5V seems too low...
Can you take the L298 input pin high (5V) with a wire?
Maybe first remove the wire from arduino....

How have you ensured 100% duty cycle -- feeding PWM signal or fixed logic voltage at the appropriate control pin of the Motor Driver? Please, post your sketch. Perhaps you know that with input supply of 12V, there is about 4/5V drop across the power transisitors of the driver; as a result, the Motor gets about 7/8V at 100% duty cycle.

Its really long idk if you wanna read that but ive used my machine with this code for weeks now and it worked perfectly fine. From one moment to the other my dc engines didnt good the full voltage anymore

erik3dprints · September 23, 2023, 5:54pm

Ive tried that and i only get about 1.5 to 2.5 Volts. Ive never measured that before i had the problem but from my knowladge and Arduino PWM pin should give 5V at max duty cycle

gilshultz · September 23, 2023, 6:52pm

Can you post an annotated schematic showing all connections, power, ground and power source(s).

2112 · September 24, 2023, 9:19am

Are you saying you removed the Arduino from the L298 inputs, applied 5V to one of the L298 inputs and THAT input measures appox 2V? If so, your L298 input has an active short.

A schematic and troubleshooting details would be helpful
