All types are supplied uln8203a an lead plastic DIP with a copper lead form and feature the convenient input-opposite-output pinout to simplify board layout. If the digital pin is Low 0 Vthen the connection to GND will be off, and there will be no current flowing through the circuit. Is the attached schematic correct?

Using a ULNA to control a DC motor – techtutorialsx

What is that symbol between the coontroller and the ULN pin 1? If the digital pin of the Arduino is High 5 Vthen current will flow through the circuit and the motor will operate.
