What is Arduino, and why it is perfect for learning robotics
Arduino is a small, cheap board that reads sensors and controls motors, lights and servos. Here is what it is, what it is good at, and where to start.
Arduino pins: digital vs analog, explained simply
Digital pins read on/off, analog pins read a range of values. Knowing which is which is the difference between a button and a light sensor working.
PWM explained: how to control motor speed and LED brightness
PWM switches a pin on and off very fast to fake an in-between voltage. It is how a digital board sets a motor to half speed or an LED to half brightness.
Reading sensors with Arduino: the pattern that always works
Almost every sensor follows the same pattern: wire power and ground, read a pin, convert the raw value, filter the noise. Learn it once, use it everywhere.
Serial communication: how Arduino talks to a computer
Serial sends data one character at a time over a wire. It is how you debug an Arduino and how a robot's boards talk to each other.
What is a Raspberry Pi, and what can you build with it
A Raspberry Pi is a full computer the size of a credit card. It runs Linux, cameras and AI models, which makes it the brain of camera-based robots.
