It may be a University project. I would try to make it robust but the most important thing is your "7 days left to complete the project"
For a practical device to use in a real car I would want to assemble with mating pcbs and soldered joints. e.g. with Protoshield or Protoboard.
It's just a first yr Intro to Mechatronics (arduino), so making the enclosure, assembly is not in the criteria. I did choose a project that is quite hard itself.
Although this will be my long term project, I'll definitely getting an enclosure going.
Hear is my project planned setup:
12V - 5V USB converter connected from car battery, to Mega board.
Should I power via jack or USB?
Oil Temperature Sensor:
-Ground wire - I can wire this to nearby ground, or I can run it back with 5V wire to Arduino.
-5V wire.
Oil pressure senor:
-Ground
-Signal
-5V
3 wire loom, so run back to Arduino.
Oil sandwich plate to mount inbetween oil filter and sump for the sensors.
Ground wire from Arduino to car body.
I have a fresh Uno proto board. Would you like me to use it?
Any other suggestions?
I also have a Nextion Display arriving in the next day or two. Seems like it is easier to display via its program. I'm might consider using it.
Thanks alot.
