comment how do i fix my arduino once i connected a motor directly to it?
@OlinLathrop who's being disrespected here? Do you realize that not everyone is a native English speaker? Instead of trying to understand OP, you are just down right insulting him.

comment How to properly power sim800l module?
Thanks for such detailed explanation.. I've tested the current capability of my reg. circuit using a dummy load and a multimeter and it's supplying well over 2A. also my laptop charger is a genuine one with rated 4.5A capability. I also tried with thicker wires and adding a capacitor bank at module side without success. I don't have access to an oscilloscope anywhere, but I'll try the method suggested Chris.

@MaNyYaCk Yes you are right. but the problem is, the voltage doesn't go below 3v it goes to about 3.8v.

@SamGibson I don't have an oscilloscope :( But I've measured the voltage when it's powered and I've noticed that voltage drops from 4.2v to about 3.8v for a brief time when it restarts. I don't know why this happens since I'm supplying 3 amps of current.

@MaNyYaCk No. It just shutsdown without any signal. then it re-starts after a second or so.

Your question already has the answer you're looking for... and opinions are off-topic here.

comment Electronic devices in outdoor use
I would suggest using a sealed box with some sort of heating mechanism coupled with a temperature sensor to keep the temperature well maintained for smooth operation of the Pi... About the power supply, It should be fine outdoors as long as you keep it away from direct sunlight and rain.
