Problem found I think - or at least I've found a problem. Checked all the DIO's on the Arduino - everything as it should be. However I've found that with everything else disconnected, just the L298 Motor Driver plugged into a 12V power supply - the 5V output pins actually supply 12V (see photos). In...

Are you saying that even with both jumpers removed the Arduino can't drive the two inputs to the correct state? Yes this is true. It seems that manipulating the jumpers is the only way to control the state of the pins - whatever combination of jumpers is used, the arduino has no control over them. ...

Hi Andrew, Thanks for your response, yes I am slightly confused - I have checked and all four pull-up resistors have 102 on them. It is definitely that the arduino can't 'override' the voltage of the motor driver - I have checked again and when disconnected, the arduino outputs are as they should be...

Hi Guys, I'm new to Arduino, having just started out on my first project a couple of weeks ago. I am trying to drive a DC Motor using the Arduino Uno R3 via a Motor Driver board based on the L298 Chip. My basic prototype circuit can be seen in the attached photos. I have connected ENA to Pin3, IN1 t...
