Hello everybody,
I'm starting a new project in which a Moteino will be involved. The project will be a controller for switching ON/OFF the PTO of a truck. The PTO (Power Take-Off) is mounted on the one of outputs of a automated gearbox, so the controller will be dealing also with the gearbox. So in order to deal with the safety issues I have to monitor some condition of the vehicle (vehicle standstill, parking brake engaged, engine running, etc..). These conditions are 28V analog signals so I want to ask more experienced with electronics guys which is the best way to hook them to moteino because obviously this little guy expects 3.3V signals? Should I use voltage divider or relay or something else?
For this moment this is what is bothering me. In the meantime I'm writing the logic for controlling the PTO valve. Any help will be appreciated.
Thanks in advance
