Arduino resets when signal sent to relay - Project Guidance

Per the diagram below, I have created a circuit which turns relays on and off based on button presses from an app. Here is the setup: SETUP: 12.5V power source (car battery) 10V regulator between 12.5V battery and Arduino Gnd on Arduino to Gnd on 8 channel 5V relay 5V on Arduino connected to Vin on Relay HC-05 relay module connected to ground and Vin on Arduino 12.5V from battery connected to NO pins on relay board Ground from 12.5V battery connected to NC pins on relay board PROBLEM
