I look to complete a project on my car utilising Arduino to provide some intelligence. some jumps of logic below but bare with me:
as the Vehicle will provide power from 12VDC to ~14.8VDC looking to a pre-made solid state power module which can deliver power to the Arduino/s
Enclosures: I would like have the final build in a at least IP67 enclosure. any out there for arduino projects (note space is at a premium in the vehicle)
Project A -door lock project-> on receiving and 12VDC to ~14.8VDC trigger - essentially triggers a 12v relay to earth to lock the doors when a travelling at a speed of say 12 miles and hour. The input is a pulse output from the speedometer controller (2,000 or 4,000 pulses per mile) - are there any off the shelf units that could fill such such (programmable)
Project B - Wiper timer unit ->this unit again triggers a 12v relay to earth based on an interval and time. once it receives an input of 12VDC to ~14.8VDC it would commence preset (programmed) interval and time (say every 4 seconds tigger the relay for 2.5 seconds which is to earth) - pretty basic - again any off the shelf units which could do this?
Looking for some fairly basic stuff here- off the shelf HW modules are better if at all possible
the input triggers for these as simply 2VDC to ~14.8VDC + - for example Ign switched to ACC for the door lock project and Column switch set intermittent wiper position
