Robot build guides that actually work
Eight guides, one philosophy: exact parts lists with Indian street prices, wiring tables that explain the why, complete tested code, and the troubleshooting sections other tutorials skip. Follow them in order or jump to what you need.
Arduino basics → robot car → line follower → obstacle avoider. About three weekends, roughly ₹2,000 all-in.
Foundations
The concepts every robot build stands on — start here if you are new.
Getting started with Arduino
Install the IDE, upload your first sketch, wire an LED and a sensor, and learn the handful of concepts every robot build uses.
45 min · Read guide →Robot sensors, explained
What each common sensor actually measures, what it costs, its gotchas, and which project it belongs in.
20 min read · Read guide →Motor drivers: L298N vs TB6612
H-bridge theory in plain language, and the honest comparison: when the ₹100 L298N is fine and when the TB6612 is worth it.
15 min read · Read guide →Builds
Complete robots, from parts list to troubleshooting. One chassis, many robots.
Arduino robot car (2WD)
The classic first robot: full BOM, chassis assembly, L298N wiring table, battery advice, and a reusable drive() function.
2–3 hours · Read guide →Line follower robot
Add two IR sensors to the robot car and follow a black track — then graduate to PID control for competition speed.
1–2 hours · Read guide →Obstacle-avoiding robot
Mount an HC-SR04 on a servo, scan left and right, and let the car roam a room without hitting anything.
1–2 hours · Read guide →Roadmaps
Zoom out: what to build, in what order, and why.
