Your first moves.
Don't start from scratch. Start from here.
Learn the sense-decide-act loop before building anything that moves
Wire an ultrasonic sensor to an Arduino and write code that lights an LED when something comes within 20cm. This single exercise contains every concept in robotics.
Understand voltage, current, and power before connecting anything
An Arduino cannot directly drive a motor — motors draw more current than the microcontroller can supply and will damage it. A motor driver board sits between them, taking power from a separate battery.
Build a line follower as your first moving robot
A wheeled chassis with two infrared sensors that follow a black line on white paper covers sensor reading, motor control, and real-time decision-making in one project. Tuning it to follow smoothly rather than oscillate introduces proportional control — the foundation of PID, which governs almost all real-world robot behaviour.
Use a breadboard before soldering anything
Breadboards let you build and modify circuits without soldering — errors are fixed by moving a wire, not desoldering joints. Confirm a circuit works on a breadboard before committing it to solder.
Read the datasheet for every component you use
Datasheets specify operating voltage, current draw, pin functions, and communication protocol for every component. Reading one before wiring prevents damage and missed capabilities.
Document every build with wiring diagrams and code comments
A robot with undocumented wiring and uncommented code is a future debugging nightmare. A rough wiring sketch and brief code comments cost ten minutes per build and save hours when something breaks weeks later.
