I am making a bot capable of solving a maze.

I will explain the setup first. There is a 18650 3.7V battery, using a XL6009 DC-DC boost switching regulator, like this one - https://www.amazon.com/Converter-Voltage-Adjustable-Step-up-Circuit/dp/B06XWSV89D/ref=sr_1_3?crid=JWPQ5AXIRXAS&keywords=boost+converter&qid=1583560714&sprefix=boost+co%2Caps%2C439&sr=8-3 , i boost the voltages upto 9.5V. Then i make 2 parallel lines. One goes to the Motor Driver voltage ( motors work fine at 10-12V). The other end goes to the Vin of the Arduino.

When i attempt to test the motors, the arduino sort of resets everytime although it works fine if i test some other peripherals and disconnect the motor driver and hence the motors.

Again the motors work fine, if i power the arduino separately like from a 9V battery keeing the rest of the ckt as it is.

what am i doing wrong  ? will connecting a linear regulator like 7809 / 7805 in series before powering up the arduino help ?
