L239D motor driver not able to drive motors Iam making a line follower robot , the issue is coming when making motors run.The L239D module has 4 inputs pins ( to control two motors) , 4 output pins (to drive motors) , and 6 power pins (5v,5v,GND,GND,9/12V,9/12V) . I have used one 5v pin to connect it to ardunio 5V supply and one of the 9/12v pin to series of two 9v battery. The motors are running low and when it is on ground the line follower not able to move. I even tried 3 9V batteries in series to make up the voltage 9+9+9=27V but not helping. Any help Thanks in advance.
I guess using 9 Volt battery in parallel will do your work because if the motor is moving as you quoted above means it is getting the voltage but not enough current to drive it, please connect the 9 volt battery in parallel and it will work for you
