Hello every, I received my FEZ Hydra kit for Christmas and I’ve got it set up and running and I can do some simple things with the joystick, the led and the light sensor. All is well on that front.
My next big step is that I want to use the Hydra to “read” voltage levels from sensor in my car. It’s an ODB1 car and I’d like to start off with some simple items like the fuel level sensor, or the engine coolant sensor. The sensors put out a varying voltage from 0 to 5 volts.
Can I simply tap into the sender wire and read the voltage, and if so, what sort of module would I use to do this?
I have a second question too… the ECU in my car has a usb (serial) connector that I use to connect to my laptop. I’ve written software that can request and read the data. I should be able to do the same thing with my FEZ Hydra if I can use the USB Host Module at http://www.ghielectronics.com/catalog/product/270. Does this module work with the FEZ Hydra?
Last question… how do you get a clock (for time keeping purposes) on the Hydra?
Thanks in advance.
