Try it yourself
Change an input. See what follows.
A simplified learning model. Values describe the model, not a connected robot.
Working Principle
Arduino is an open electronics platform that combines a microcontroller board, simple programming tools, and many input/output pins for learning and prototyping.
Step by Step
Write a sketch in the Arduino IDE.
Upload it using USB.
The board runs setup once and loop repeatedly.
Pins read sensors and control outputs.
Concept illustration; component appearance and scale are simplified.
Practical learning notes
Key idea
Arduino Nano is a small controller board commonly built around ATmega328P, with digital I/O, analog inputs, PWM pins, UART, I2C, and SPI.
Use in robot
Nano reads sensors, receives commands, and sends control signals to L293D, servo, and modules.
Safe wiring
Do not power motors from Arduino pins. Use a regulated 5V logic rail and a separate motor rail through the driver.
Classroom check
Upload Blink first, then read one sensor, then control one motor channel before building the full robot.
