Tell us about yourself!
Im trying to use the TX module in a project with 12V supply. But now I don't know what voltage is required to set HIGH on the data pin? Is it a percentage of the VCC voltage or is it a fixed limit no matter what the VCC is supplied? Dose anyone know?
Just hooked up my sensor following your tutorial, slightly modified. (No LEDs) And combined it with the "Graph" sketch to plot distance in Processing. Super simple! Thanks for a great and easily understandable tutorial!
