Coding with No Electricity

Well, here in Southeast Arkansas, it looks like I will be without power within 24 hours. This will most likely last anywhere from 3 days - 2 weeks depending on the severity.
Now, to my question.
Can anyone send me any pdf’s about PIDS, sensors, odometry, etc. So I can print them out and read about them during my boredom that will be no power in very cold weather?


Here’s a doc for Odometry that was released a couple of years ago


Thank you, thank you so much.

2 useful PID documents

be sure to prepare some power banks, good luck




A lot of example code for PID here:

Most of the links should take you to printable locations

Just want to say… put your laptop on low power mode and conserve as much battery as you can considering their won’t be power for a few days.


Adding onto this, and what Ryan said, do both of these. Don’t take your computer off of low power mode.


ive been without power since 6 am (in austin), and your car is not as good at charging stuff as you think. dont let your electeonics die.


If you do not have EV-only car, open garage door, back up car so exhaust outside (not obstructed by snow pile) if you need to use car to keep warm. Carbon monoxide kills, and has already for those trying to keep warm by running car engine.

Not running car engine, you can use car battery for lights and radio - bring lots of blankets if car is in garage with doors closed, can keep warmish…

Frozen pipe prevention - keep a tap running slow drip - helps internal pipes… Baseboard water heating - make sure to keep all cabinet doors open - and doors - average out remaining heat in house. Close all drapes/curtains… use gaffers/shipping tape to close all gaps in doorways to exterior.

Be careful with interior heating/cooking fuel - do not create excessive carbon monoxide… be sure carbon monoxide detectors work.

So much to consider - but keep safe - best way is to think about what each action you make has.


I’m from the north and get over 77 inches of snow per year (on average). That isn’t to belittle what you’re currently experiencing, but just know that it will eventually pass. A little bit of a shift in perspective is all it takes to boost your morale, and I say this because power outages and snow storms are totally normal where I live (in fact, I had to ride my bike to class in the middle of a blizzard). It’s not the end of the world if you go a few days (maybe even weeks) without technology. Think of it like a break from your typical routine and an opportunity to read a book maybe, solve a puzzle, whatever floats your boat.

Just thought I’d leave this here to let people know that while this is highly unusual in the South, you aren’t alone. And yes, I know this might seem obvious, but it should be stated anyways.

I think there are a lot of things that are “obvious” to those in the north - like snow loads on roof structures … but so happens that when someone not from the north designs a stadium roof unaware of snow loads, then catastrophe strikes and you have structural failure. Southward, problems lie with frozen pipes - well in normal times it is truly an unexpected situation … ditto for warming up with car in interior space with no ventilation - CO rates high, and human life lost.

stay safe - help one another out

as bad as that sounds, I dont think its quite as catastrophic as whats up in texas rn. Something like half the state is powerless. Trees are falling from the ice weight. Peopke who don’t know how to drive in this weather are on the roads, and there are no plows. We are cold and trapped at home, and I hope OP is safe and warm.

Austin is getting it really bad. We are in Galveston, and we just got power and water for the first time in 60 hours, but we haven’t lost it yet. It’s gotten cold for sure down here, but not that bad. Here is a map.

So what you’re telling us is, the panhandle’s where it’s at.

I would use it as an opportunity to work on Flowcharting and pseudo-code.

Identify a suitably complex task and break it down into flowchart steps. Then use a form of Pseudo-code. The difference is that pseudo-code isn’t concerned with precise syntax.

(Keep in mind, I just started with VEX. However, the principles don’t change)


Yeah, save your energy. You could use a laptop with power to charge a phone and keep updated with when you are going to get power back and stay in contact with your family. That is if you still have service.
