Hello Basic question. During the course of looping my program and performing digitalWrites to pins, if I write a HIGH to a pin so that it turns on a transistor, do I need to keep writing HIGH each time through loop to maintain the pin in its HIGH state thus keeping the transistor switched on? Or …

When to write pin high/low?

you only write to change its state.
