Building things across software and hardware.

This is my engineering log:
- backend (Java/Kotlin), iOS, and general programming
- microcontrollers, Arduino, Raspberry Pi
- small DIY projects and experiments
- tools, setups, and things I’m learning

Hi everyone! Nice to see you here.

A couple of days ago, my son asked me about electricity and how traffic lights 🚦 work.

I didn’t think for long and decided to build one together - obviously a small and much simpler version of it 😊

Let’s go 🚀

I also received a beautiful box of different things. There are resistors, LEDs, breadboard and many many more. We’ll try it today 🤤

The breadboard is quite low on quality
I’ve tried to install the power supply on it but it doesn’t fit. Probably the metal holes are defected.
Based on my previous experience it should go easy in, but it should. I my case it pushed out the back side 😖

The boss is here, well it’s time to fire the keyboard and write the traffic light program
But first, we try to blink a led. Blinking LED is “hello world” in microcontroller world
