If you can blink an LED, you can change the world.
But I believe, If you can read the manual, you can change the world.
Back in my college days, I was interested in Embedded System and Internet of Things, and loves to spend my pocket money on building new things.
I used to run the simulation on Proteus, a software well known for simulating things and then on real device.
On one occasion, I was building a scrolling text animation on dot matrix display using Arduino, which was working fine on Proteus, but failed on real device.
Frustrated, I turned to my mentor, a seasoned veteran. His advice was simple:
"Dakshim, have you read the display manual".
Me: But it is working fine on Proteus.
He: Read the manual first.
It turns out to be a common issue with that specific display that was mentioned on the very first page of the manual.
Decade passed, but lesson remained. Read the Fabulous Manual
