now its okey. when i power motor driver it lit up arduino led but not arduino
But main problem is i can power teds for sensor they are dim when powered with 9 v no problem in usb
Its problem when there are more than 2 sensors
is there problem arduino for providing power
is it possible to provide power to arduino throgh it 5v pin because when i connect vcc pin to arduino then arduino start up. And circuit can i run without connecting both ground
Main thing is please suggest that do i need to provide seprate power to sensors
