What is the best method to view the values a sensor is sending to my controller? Do I have to set up some sort of wireless something or other to view what the controller is receiving? Is this what UART is for? Can I use a digital display to send the values I want to observe to?
With photo sensors, like the ones created in the $50 tutorial, what value is being sent to the controller. It seems to me it would be the voltage with the resistance from the photo resistor applied. I am trying to determine the range of values I could get from a photo resistor in what ever value the controller would receive.
Thanks very much for your help,
