Week 7 | Learning Robotics, Math & Arduino

This week I built an automatic night-light system using an LDR module.

By reading the analog signal from the sensor, the Arduino now switches the light ON when the measured value crosses around 900, which means the environment is extremely dark.

Seeing a simple idea turn into working hardware still feels magical.

I’m really enjoying the entire process of experimenting with Arduino, understanding sensors, and watching small circuits come alive. Many more exciting builds are coming next.

Alongside electronics, I’ve been diving deep into math and theory.

This week I studied:

imaginary and complex numbers
adding and subtracting complex numbers
factoring monomials
greatest common factor
factoring using structure
polynomial factorization and identities
geometric series
polynomial division
dividing quadratics by linear factors
dividing polynomials by linear factors
polynomial remainder theorem
zeros of polynomials
positive and negative intervals of polynomials

I also explored electromagnetism and number systems based on decimal (10), octal (8), and binary (2).

Binary especially captured my imagination – the way entire digital worlds are built from just 0s and 1s is mind-bending.

Step by step, the foundation is getting stronger.

Every week feels like building another layer toward becoming the engineer and inventor I want to be.

More projects, more learning, and more momentum ahead.
