My First Lines of Code

A short walk down memory lane to see my first lines of code written in BASIC just to make an LED blink for a simple little hello world.

My First Lines of Code

Technically I had played around with coding before this point, but this was the first time I solidly coded and the beginning of what would become my career.

All through high school I took electronics classes mostly full of resistors, switches, and LEDs. It wasn't until later that coding was introduced to us and I had an incredibly supportive teacher to whom I credit for getting me into my career. (By chance I was able to give back as I got to work with him professionally after graduating university.)

It was this teacher in February 2008 that gave each of us a development board which had LEDs, piezoelectric speaker, and headers for the ATmega32L chip.

A very 2008 looking photo of the development board.

We crimped and soldered our own serial ports, which often broke due to poor manufacturing and abuse, and connected those to Windows XP computers.

A blurry hand made F-tier quality serial port cable.

On these Windows XP machines, we used BASCOM AVR IDE to write BASIC for the chip.

And in this I present, pretty much the first piece I code I wrote. While the file was templated nicely for us - it was my first hand written "hello world" by toggling an LED on and off in section 12:

From here we moved to messing with:

  • More LEDs (turning them on and off in a Knight Rider style)
  • Dot matrixes
  • LCDs
  • Piezos (for six months+ someone was always playing the Barbie Girl midi)
  • Switches
  • Photoresistors
  • And more misc. components

Growing up I had always wanted to do something in science or technology, but taking this class back in 2008 four times a week really shaped my future. It's incredible to still have these files and the memories from way back when I was a completely novice programmer. ๐Ÿ‘€ But don't let my job title fool you, I'll always be ready to learn as a novice.
