I'm new to PD and am interested in using range finders in a project. I know that it is a simple affair to hook up an IR Sensor but that it's far more difficult to get the ultrasonics, such as the ones by Parallax, to play friendly with PD. In my research I came across the Maxbotix, which is supposed to be easier to use (https://www.sparkfun.com/products/639). The interface output formats included are pulse width output, analog voltage output (Vcc/512 volts per inch), and serial digital output (9600 baud). Does anyone have experience with these? Are they plug and play with pduino?
