What You Can Expect Here
Our goal is to make robotics projects easier to start, whether you are a teacher, hobbyist, or prototyper. You’ll find clear wiring diagrams with pin labels and voltage notes, short code examples you can adapt, and classroom-friendly exercises and checklists.
We’re not experts — just sharing as we learn. Treat these guides as practical starting points and adjust for your parts, power setup, and environment.

The Sensors Hub covers ultrasonic distance, line tracking, IMUs, and more. In Servos & Motors, you’ll find micro servo basics, DC motors, and PWM control patterns.
Microcontrollers includes pin maps and I/O level notes for Arduino-compatible boards. Project Resources provides print-ready PNG, SVG, and PDF diagrams.
Official Resources
- Arduino Documentation — board pinouts, libraries, setup guides
- Community Project Hub — step-by-step community projects
- Arduino Downloads — IDE, drivers, and board definitions
Example Guides
For ultrasonic distance sensing (such as the HC-SR04), we show wiring for VCC, TRIG, ECHO, and GND, note when level shifting is needed, and include code with basic timeouts and averaging.
For micro servos like the SG90, we cover 50 Hz control, gentle startup moves, and using a dedicated 5–6 V supply with a shared ground.
Line following with a triple IR sensor includes sensor height, matte line material, and ambient light shielding. Start with simple majority voting across three sensors, and consider PID later for smoother tracking.
We also touch on power and grounding — shared ground, suitable regulators, and decoupling.
