Hello all,
I want preface this by saying this is my first "Electronics" project so my knowledge is lcking in many areas, but with that said, the problem:
My car with randomly drop power to the arduino.
I have an arduino R3 uno as my workhorse, that is being powered by a tapped accessory fuse from my cars (subaru wrx if that matters?) fuse box. From my understanding the arduino has a voltage regulator that drops the 12v to a safe voltage for the board.
I then have two identical breaboarded circuits that take the voltage input to the turn signal (12v) and drop it to ~5v and send it as an inout to the arduino.
The code on the arduino lights up two LED strips solid when theres no turn signal input and then flashes he respective strip when the input signal goes HIGH.
After the system is up and running for about 30-45 sec the arduino will flash an orange led on the board and the LED strips will turn off. Within a few secs he board/LEDs are back up and running. I have tested this with a 9v battery as power and dont have this issue, so im assuming its either something to do with the output power of that fuse? Im not sure its that because the arduino board doesnt go fully off it keeps the green LED on throughout this process. The fuse gives power through the barrel jack voltage reg and is grounded through a screw nearby. All my grounds are routed to the ground from that screw. Any thoughts on what may be the issue? If more info is needed let me know. Thanks in advance!
