Nothing feels worse than getting a new Arduino board and then managing to destroy it after a manner of minutes.
This episode discusses five ways you can damage/destroy an Arduino – so you can avoid them!
Mistake #1: Shorting I/O Pins to Ground
Mistake #2: Shorting I/O Pins to Each Other
Mistake #3: Apply Overvoltage to I/O Pins
Mistake #4: Apply External Vin Power Backwards
Mistake #5: Apply >5V to the 5V Connector Pin
We also learn about an Arduino UNO derivate designed to protect against each potential mishap.
Everything has limits.
If you try to drive a semi-trailer full of gold bars over a tiny bridge, you could exceed the weight limit of the bridge, destroying the bridge and probably screwing up the semi-truck too.
Or, if you drive a car at 100mph and then try to stop it within ten feet of a brick wall – you’re probably going get all smashed up – and it’s not the car’s fault – there are certain limits the vehicle must be operated within.
The Arduino is no different. It has limits that it must be operated within. If you exceed those limits expect that you will damage or destroy an Arduino board.
If you know the limits – if you’re equipped with this knowledge – then you’ll be able to protect yourself from making the mistakes that might lead to destruction.
Rugged Circuits: How Not to Destroy an Arduino
All of the material in this video is based on a really great article written by a company named Rugged Circuits.
The Ruggeduino protects against every form of destruction we talk about in this week’s video.
It’s kind of like the superhero of Arduino derivative boards – it’s pretty much invincible. It prevents simple mistakes from destroying it.
Here is a link to the article (It’s a great read and I highly recommend checking it out):
In next week’s episode, we will talk about 5 more ways to destroy an Arduino!
If you have ever damaged, destroyed, or deep-fried an Arduino board, I would love to hear about it in the comments!
