Spent my day designing the drone. I started with the basic motor and propeller design on CAD.

Spent two weekends to build this. 7 segments and 6 digits. Will be building a clock. I should have designed it before started soldering. Soon enough I realised i cannot connect further without jumping wires over each other. It looks much better though than my last AC to DC converter.

New stuff. Ordered a few boards as i wanted to build a transistor array module. And a resistor array. Its such a cool component. I dont need my messy resistor array anymore. And another breadboard. Current one does not have enough space for larger circuits.

Built a 7 segment display counter using stm32f401 microcontroller. And killed segment “a” too by mistake. Its not that bright anymore.

My traffic lights project is complete. This is from a pov of a pedestrian. I have added a pedestrian buzzer as an accessibility feature.

I blinked an user LED and blinked a bunch of external LEDs to form a pattern. Next is to turn into traffic lights.

Started off my embedded journey with STM32.

This little guy was sitting in my house since so many years. Ordered it during covid and never spent time to learn it. Its raining since morning and I thought to start learning it again.

And my 7 segment display driver is readyyyy !! 🕺🕺It takes in 4 bits input and produces 0-9 numbers on the display as output.
