![]() ![]() It would also be another reason to need to connect the ground. Is that white wire from the L298N board to Arduino Vin intended to power the Arduino? If so, that needs to come from the 12V connection (which is really 9V). Of course, we are driving 2 motors instead of one, to give 2 wheel tank style “skid” steering, instead of using the servo. Our “CARBOT” runs from 9 volts as well, but in the form of 6 AA batteries, instead of a single 9V battery. Powering the motor from a 9V battery may not work well, depending on the motor. Instead, we added 3.3V regulator powered from the Arduino 5V line. They use too much power to be reliable when powered from the Arduino 3.3Volt line. We have a similar introduction project using the NRF24L01 radios. But a ground from the L298N board needs to connect to one of the Arduino ground pins. There needs to be a “closed loop path” for the signals.Īll of the Arduino board ground pins are connected together internally, so one or more of them can be used in any combination. You need to have the Ardunio ground connected to the L298N board ground for the Ardunio data signals (to the L298N board) to make sense.
