I watched the tutorial
and I managed to make the L298N chip
to work with a small vibration motor, but I have difficulty running a pump
1) I have a 5V supply (which actually measures 5.7V). I attach my pump to it an the pump works.
2) I connect my supply to VCC and +5 on L298N and when I attach a small vibration motor to the outputs the motor works.
3) I replace the small motor with pump and pump does not work, it tries to rotate and produces a constant quite noise.
What am I missing here?
I do know the pump is working, and L298N is wired properly. When I measure the voltage across the pump inputs it is 4.6V, while when a pump is not connected it is what the voltage supply gives 5.7.
