Sorry, I can't figure out the questions here. A few suggestions on how to post more effectively:
1. Use punctuation. Sentences and paragraphs help readability. 2. Be more specific about: what exactly you did (include circuit diagrams, code snippets, datasheets wherever applicable), what you expected to happen, what happened instead. The way you asked the questions, I have no way of telling: 1. Which ultrasonic sensor you're using. 2. How you connected it electrically. 3. What your code does with it. The only useful thing I could understand from your question is that when you open a digital output with *true* it will be initially set to, er, *true*, even if you don't write(true)...
